Email Settings GuideQuick answer: Aruba mail on your own domain uses imaps.aruba.it for IMAP on 993, pop3s.aruba.it for POP3 on 995 and smtps.aruba.it for SMTP on 465, each over SSL. A free @aruba.it or @technet.it mailbox drops the s. Sign in with the full email address and your Aruba mailbox password. Not sure which host? See which server to use.
What Changed Recently#
Aruba uses a different mail server for each kind of mailbox, which trips up many setups. Here is where Aruba Mail stands today and what it means for your setup.
Worth knowing
The s in imaps.aruba.it matters. A mailbox on your own domain uses imaps.aruba.it with an s. A free @aruba.it or @technet.it mailbox drops the s and uses imap.aruba.it. Match the server to your address.
Worth knowing
IMAP is an added service on a domain. If IMAP will not connect, switch the IMAP service on for the domain in the Aruba panel first. POP3 and SMTP work without it, but IMAP needs it active.
Worth knowing
PEC uses its own servers. A certified PEC mailbox runs on imaps.pec.aruba.it and smtps.pec.aruba.it, not the standard hosts. This page covers standard Aruba mail, not PEC.
Before You Begin#
Handle these two basics before anything else. Skip them and your email app will reject the connection even when every server value is correct.
1. Create the mailbox
Add the address in the Aruba panel and set its password. Check that the IMAP service is active on the domain.
Where: Aruba panel then Email
2. Match the server to your address
A domain mailbox uses imaps.aruba.it. A free @aruba.it mailbox uses imap.aruba.it. PEC uses imaps.pec.aruba.it.

About Aruba Mail#
Aruba is an Italian provider founded in Arezzo in 1994 and now headquartered in Ponte San Pietro near Bergamo. Aruba runs its own mail servers. The server you use depends on the kind of mailbox.
Aruba S.p.A. has hosted domains and email since 1994. It grew from a start in Arezzo to a head office near Bergamo and is the best known name in Italian hosting and PEC certified email. For a mailbox on your own domain the incoming server is imaps.aruba.it and the outgoing server is smtps.aruba.it. You sign in with the whole address and your Aruba mailbox password.

Find Your Settings#
IMAP on an Aruba domain is an added service. Turn it on for the domain, then read the values in the panel.
- Sign in to the Aruba panel at admin.aruba.it.
- Open Email then your mailbox.
- Check the IMAP service is active on the domain.
- Use imaps.aruba.it and smtps.aruba.it over SSL in your app.
Aruba IMAP Settings#
IMAP is the incoming choice for an Aruba domain mailbox. Mail stays on the server, so webmail and your phone read one shared inbox. Aruba runs it on imaps.aruba.it over 993, once the IMAP service is active on the domain.
| IMAP Server | imaps.aruba.it | |
| Port | 993 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full email address, including @yourdomain.com | |
| Password | Your mailbox password | |
| Authentication | Required |
Aruba POP3 Settings#
POP3 downloads mail to 1 device. Pick it only if you want a local copy on a single computer. Not sure? See the comparison below.
| POP3 Server | pop3s.aruba.it | |
| Port | 995 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full email address | |
| Password | Your mailbox password |
Aruba SMTP Settings#
SMTP handles outgoing mail. If you can read mail but not send it, the problem is here.
| SMTP Server | smtps.aruba.it | |
| Port (SSL) | 465 | |
| Port (STARTTLS) | 587 | |
| Encryption | SSL or STARTTLS (required) | |
| Username | Your full email address | |
| Password | Same as incoming mail | |
| Authentication | Required. Switch on outgoing server authentication in the client. |
465 with SSL. Many home connections block port 25. Aruba SMTP always requires authentication. A free @aruba.it mailbox can also use 587 with STARTTLS.
Check Aruba IMAP Settings Online#
You don't need to download anything to check Aruba IMAP settings online. This page is the lookup: every value is verified, current and copyable straight from your browser. Not sure which Aruba server your address uses? Enter it below to check in a moment.
Does my email address use these settings?
Runs in your browser only. Your address is never sent anywhere or stored.
Want to verify the account itself before configuring an app? Sign in at Aruba webmail, which confirms your address and password work. If webmail.aruba.it opens, any email app connects with the tables above.
Look Up IMAP Settings for Any Email Domain#
This page covers Aruba. For every other address, work email on a company domain included, we run a free online lookup database: imapsettings.com.

Complete email settings database, by Univik
Enter any email address and get the incoming and outgoing server settings for that domain in 1 step:
Your address is used only to find the settings for that domain. Nothing is stored or shared.
Username and Password#
Both come from the mailbox itself. The username is the whole email address and the password is the one you chose when you created the address in the Aruba panel. A standard Aruba mailbox uses no app password.
Username is the full address
Type you@yourdomain.com in full, with the part after the at sign. Aruba turns down a bare mailbox name.
Put the same Aruba address on both incoming and outgoing.
Password is the mailbox one
This is the mailbox password you set in the Aruba panel, not your Aruba account login. If two factor is on, an email client can need a dedicated password you create in the panel.
The two factor prompt on the Aruba account guards the account. A mail client uses the mailbox password. If two factor is on, it can need a dedicated password.
Set Up Aruba in Email Clients#
The servers and ports are always the same. Only the menus differ. Jump to your app:
Outlook (Windows and Mac)
- In Outlook select Add Account, then turn on manual setup under Advanced options.
- Choose IMAP and set incoming to
imaps.aruba.iton 993 with SSL. - Set outgoing to
smtps.aruba.iton 465 with SSL. - Enter the full address and mailbox password when Outlook prompts you.
- Send a test message to yourself to prove both paths.
Apple Mail (macOS)
- In Mail select Add Account, then pick Other Mail Account.
- Give your name, Aruba address and password, then continue.
- Enter imaps.aruba.it for incoming and smtps.aruba.it for outgoing, both with SSL.
- Keep the SSL ports so nothing sends in plain text.
- Save and wait for the mailbox to load.
iPhone and iPad
- In Settings open Mail, then tap Mail Accounts and Add Account.
- Tap Other then Add Mail Account and fill your details.
- Keep IMAP chosen and put imaps.aruba.it for incoming and smtps.aruba.it for outgoing.
- Leave the secure ports iOS fills, since Aruba expects SSL.
- Tap Save and let iOS run its check.
Android
- Open your mail app and tap Add account, then Other or IMAP.
- Put in your address and password. Switch to manual setup if it stalls.
- For incoming use imaps.aruba.it on 993 over SSL.
- For outgoing use smtps.aruba.it on 465 over SSL.
- Save and swipe down to fetch your mail.
Thunderbird
- In Thunderbird pick Account Actions, then Add Mail Account.
- Type your name, Aruba address and password, then Continue.
- Wait for detection, then make sure IMAP with SSL is picked.
- If detection fails, type imaps.aruba.it for incoming and smtps.aruba.it for outgoing.
- Hit Done and the folders fill in on the first sync.
Aruba Webmail Settings#
Server settings connect your apps. These controls set how an Aruba mailbox behaves on the server. They live in Aruba webmail at webmail.aruba.it, open in any browser with the full address and mailbox password.
Signature
Add one in the webmail.aruba.it preferences. The signature rides on mail sent from webmail. A desktop app keeps its own.
Vacation Auto Reply
Set an out of office reply in webmail and give it start and end dates. The Aruba server sends it, so it fires even when your machine is off.
Filters and Folders
Create filters in Aruba webmail. A server side rule sorts a message ahead of any device fetching it. A rule set inside an app only works while that app is open.
Spam and Blocked Senders
Aruba filters incoming mail for spam. Tune rules and blocked senders in webmail. Flagged mail lands in the Aruba junk folder for a look.
POP3 vs IMAP#
| Feature | IMAP | POP3 |
|---|---|---|
| Where mail lives | On the Aruba server | Downloaded to 1 device |
| Multiple devices | ✅ Everything stays in sync | ❌ Each device sees different mail |
| Sent and deleted mail | ✅ Synced everywhere | ⚠️ Stays only on that device |
| Offline reading | ⚠️ Cached mail only | ✅ Full local copy |
| Server storage used | Yes, counts against your quota | Can be freed after download |
| Best for | Phone + computer, everyday use | Single PC, local archives |
Aruba Sending and Storage Limits#
A few limits are worth knowing before you bulk forward or move a mailbox. Aruba runs standard Italian mail servers with a few rules:
| Mailbox storage | Set by your Aruba email plan |
| Username | Full email address |
| SMTP port | 465 with SSL, auth required |
| IMAP service | Add-on, active per domain |
| Encryption | TLS 1.2 or newer |
| Free @aruba.it server | imap.aruba.it, no s |
Troubleshooting Aruba Connections#
Find the exact error your email app shows, then apply the fix:
| Error you see | What it means | Fix |
|---|---|---|
| Username or password rejected | Short username or wrong password | Use the full email address with the mailbox password from the Aruba panel, not your Aruba account login. |
| Cannot send on port 25 | ISP blocks the default SMTP port | Switch outgoing to 465 with SSL on smtps.aruba.it. Aruba SMTP always requires authentication. |
| IMAP will not connect | IMAP not active on the domain | IMAP is an added Aruba service. Switch it on for the domain in the Aruba panel, then set imaps.aruba.it. |
| Server not found | Used imap instead of imaps | A domain mailbox needs imaps.aruba.it with an s. A free @aruba.it mailbox uses imap.aruba.it. Match the server to the address. |
| Cannot connect to server | Wrong port or encryption | Set 993 with SSL incoming and 465 with SSL outgoing. A firewall on your own machine can block it as well. |
| Repeated password prompt | Short username or a typo | Clear the saved login, then put in the full address with the mailbox password. |
| Messages stuck in Outbox | SMTP authentication is off | Enable "outgoing server requires authentication" with the same login as incoming mail. |
| Free @aruba.it mailbox will not connect | Used imaps instead of imap | A free @aruba.it or @technet.it mailbox uses imap.aruba.it, with no s. Only a domain mailbox uses imaps.aruba.it. |
| PEC mailbox rejected | Used the standard servers | A PEC address uses imaps.pec.aruba.it and smtps.pec.aruba.it, not the standard Aruba hosts. |
Reader Reported Fixes
Match the server to the address. A domain mailbox uses imaps.aruba.it and smtps.aruba.it. A free @aruba.it mailbox drops the s. PEC uses the .pec.aruba.it servers. The right pair clears most failed setups.
Test the login in webmail first. Sign in at webmail.aruba.it with the full address and mailbox password. If webmail opens, the credentials are right and the issue sits in the server names or ports.
Which Aruba Mail Server Do You Use?#
The server changes with the kind of mailbox. Pick the wrong one and the app cannot connect. Here is the quick call.
Own domain
you@yourdomain.ext
- IMAP imaps.aruba.it
- SMTP smtps.aruba.it
- POP3 pop3s.aruba.it
Free Aruba mailbox
@aruba.it or @technet.it
- IMAP imap.aruba.it
- SMTP smtp.aruba.it
- POP3 pop3.aruba.it
PEC certified
you@arubapec.it
- IMAP imaps.pec.aruba.it
- SMTP smtps.pec.aruba.it
- Certified email in Italy
Moving Mail In or Out?#
Aruba mail speaks plain IMAP, so a mailbox moves in or out like any standard account. On an Aruba move each folder stays on the server until the copy ends.
Take a copy first. Back up the mailbox before a move. A note that arrives mid switch can sit on either side. A copy keeps you safe.
Carrying mail across? The Univik Email Migration Tool moves each folder over an IMAP link. Give it imaps.aruba.it with the mailbox password on this side and the other account opposite.
Rather hand it off? Our Email Migration Services team runs the whole move and verifies each folder arrived.
Use These Settings in Univik Email Backup#
The same IMAP settings above let you download your complete Aruba mailbox to your computer. Univik Email Backup saves everything as PST, MBOX, EML or PDF files you keep forever, even if the account closes.
- Download Univik Email Backup and install it on Windows.
- Select Aruba from the source list. If Aruba is not on the source list, pick a plain IMAP account.
- Give the complete email address with your mailbox password. On Aruba the login name is always the whole email address.
- When the backup tool wants server details, hand it imaps.aruba.it on port 993 with SSL. Take those values straight from the IMAP table above, with port
993over SSL. - Pick a saving format and folder, then start the backup. Large mailboxes download in the background.
Univik Tools That Use These Settings#
Many people land here while migrating or archiving a mailbox. All 3 tools use the same IMAP settings from this page:
Email Backup
Download your complete Aruba mailbox to PST, MBOX, EML or PDF before switching or closing the account.
Email Backup Tool →
Email Migration Tool
Copy every folder from Aruba straight into Gmail, Microsoft 365 or any other account. No manual export needed.
Email Migration Tool →
Email Converter Tool
Already have MBOX, EML or OST files from an old export? Convert them to PST, PDF or any format your new app opens.
Email Converter Tool →Prefer to hand the whole migration to experts?
If the hostnames and passwords feel like busywork, you can let the tool handle it. Univik's migration team handles the complete project: planning, transfer, verification and a report showing every folder made it. Since 2013, for single mailboxes up to full company moves.
Email Settings Glossary#
IMAP
Internet Message Access Protocol. Reads mail that stays on the server, so all your devices see the same inbox, folders and read status.
POP3
Post Office Protocol version 3. Downloads mail to 1 device and can remove it from the server. Older method, still useful for local archives.
SMTP
Simple Mail Transfer Protocol. Sends your outgoing mail. Every account needs it next to IMAP or POP3, which only receive.
SSL / TLS / STARTTLS
Encryption for the connection. SSL/TLS encrypts from the start (ports 993, 995, 465). STARTTLS upgrades a plain connection (port 587).
Mailbox Password
The password you set for an Aruba mailbox in the panel. Your email apps use this, not your Aruba account login.
imaps.aruba.it
The incoming server for a mailbox on your own Aruba domain, on 993 over SSL. A free @aruba.it mailbox uses imap.aruba.it.
Aruba Panel
The admin.aruba.it area where you create mailboxes, set passwords and switch on the IMAP service.
PEC
Posta Elettronica Certificata, the legally certified email used in Italy. It runs on separate servers, imaps.pec.aruba.it and smtps.pec.aruba.it.
smtps.aruba.it
The outgoing server for an Aruba domain mailbox, on 465 over SSL. It always requires authentication.
pop3s.aruba.it
The Aruba POP3 server for a domain mailbox, on 995 over SSL. POP3 downloads mail to one device.
Aruba Webmail
The browser mail at webmail.aruba.it. Sign in with the full address and mailbox password.
IMAP Service
An added Aruba service that must be active on a domain before IMAP will connect. Switch it on in the panel.
imap.aruba.it
The incoming server for a free @aruba.it or @technet.it mailbox, on 993 over SSL. A mailbox on your own domain uses imaps.aruba.it instead.
TLS 1.2
The minimum encryption Aruba needs for an SSL connection. An old client that only speaks TLS 1.0 or 1.1 cannot connect.
Dedicated Password
A separate password for a mail client when two factor is on for the Aruba account. You create it in the panel.
How We Verify These Settings#
Univik builds email backup, migration and converter software since 2013. Our tools sign in to Aruba over IMAP and SMTP every day for thousands of users, so a changed server, port or login rule shows up in our connection logs before most guides notice it.
Every value on this page is confirmed with three checks: a live IMAP and SMTP connection from Univik Email Backup, a comparison against the Aruba guides and a sign in with a real mailbox using the full address. We re verify after any provider announcement and at least once a quarter.
Found something that no longer matches what Aruba shows you? Tell us and we will retest and update the page, with the change logged in what changed recently.
Help & Support
Frequently Asked Questions
For a mailbox on your own domain point your app at imaps.aruba.it on port 993 over SSL. Your login name is the full email address and the password is your mailbox password. A free @aruba.it mailbox uses imap.aruba.it instead. The IMAP settings section holds the full table.
Check the username first. It must be the complete address rather than the part before the at sign. Use the mailbox password from the panel. If two factor is on for the account, an email client can need a dedicated password.
IMAP suits nearly everyone. Mail stays on the server so webmail and your phone match. IMAP on Aruba is an added service, so switch it on for the domain first. POP3 downloads mail to one machine. Full comparison here.
Yes. The server, ports and encryption match on iPhone, Android and Windows. Only the path to the settings screen shifts by app, which the client setup guides spell out.
imaps.aruba.it, with an s, is for a mailbox on your own domain. imap.aruba.it, with no s, is for a free @aruba.it or @technet.it mailbox. A certified PEC mailbox uses imaps.pec.aruba.it. Match the server to your address.
Yes. Leave SSL set on each server so the sign in never travels in the open. Your client needs TLS 1.2 or newer for Aruba. Set a strong mailbox password in the panel.
An email client with IMAP downloads mail as it syncs, but a dedicated backup tool is faster and saves standard files you can open anywhere. See how to back up your Aruba mailbox. If you already exported files in another format, an email converter changes them to PST, PDF or whatever your new app opens.
With Aruba mail the culprit is often a lapsed IMAP service on the domain or the wrong server. Confirm the IMAP service is active and that you use imaps.aruba.it for a domain mailbox. Check what to know. Enter the whole address with the mailbox password, then 993 incoming and 465 outgoing over SSL.
A migration tool copies mail across the two accounts on an IMAP link. Give the Aruba IMAP settings with imaps.aruba.it and the mailbox password on this side and the destination details on the other. Each folder lands with its dates intact.
If setting this up feels risky or you have many accounts to move, our managed email migration service does the entire job for you.
It depends on the mailbox. A mailbox on your own domain uses imaps.aruba.it and smtps.aruba.it. A free @aruba.it or @technet.it mailbox uses imap.aruba.it and smtp.aruba.it. A PEC address uses imaps.pec.aruba.it and smtps.pec.aruba.it.
