Both platforms below use the same underlying servers described in Email client settings -- this guide is just the tap-by-tap path through each app's setup screens.

iOS: the built-in Mail app

1. Open Settings > Mail > Accounts > Add Account, then choose Other at the bottom of the list.
2. Tap Add Mail Account and enter your name, full email address, mailbox password, and a description (whatever you'd like to call it in the account list).
3. iOS tries IMAP automatically. If it can't verify the account, it drops you into manual Incoming Mail Server / Outgoing Mail Server fields -- fill them in with:
   • Incoming: imap.mila.cx, port 993, your full email and password.
   • Outgoing: smtp.mila.cx, port 587 (or 465), your full email and password.
4. Save, then make sure the Mail toggle is on for the account so it actually syncs.

Android: the Gmail app with a non-Gmail account

The Gmail app can manage any IMAP mailbox alongside your Google accounts:

1. Open Gmail, tap your profile picture, then Add another account.
2. Choose Other, then Personal (IMAP) (POP3 is also listed if you specifically want that instead).
3. Enter your full Mila email address, then the mailbox password when prompted.
4. On the incoming server screen, set the server to imap.mila.cx, port 993, security type SSL/TLS.
5. On the outgoing server screen, set the server to smtp.mila.cx, port 465 with SSL/TLS (or 587 with STARTTLS), and make sure "Require sign-in" uses the same email and password.
6. Give the account a name and tap through to finish -- it now appears alongside any other accounts in the app switcher.

Other Android mail apps

Apps like Outlook, K-9 Mail, and FairEmail all accept the same manual IMAP/SMTP settings above. Look for a Manual setup or IMAP option during account creation if the app's automatic detection doesn't recognize your domain -- it usually won't, since Mila hosts many different domains rather than one fixed one it can guess from your email address.
