Set up Mail on Mac

1. Open Mail → Mail menu → Add Account → Other Mail Account → Continue.
2. Enter your name, the full email address and the password, then click Sign In.
3. If Mail asks for the servers, fill in:
   • Account Type: IMAP;
   • Incoming Mail Server: imap.sitelyra.it;
   • Outgoing Mail Server: smtp.sitelyra.it;
   • User Name: the full address.
4. Click Sign In and choose the apps to use with the account.

Mail picks the right ports and security on its own. If sending doesn't work: Mail → Settings → Accounts → the account → Server Settings, turn off Automatically manage connection settings for outgoing mail and set port 465 with TLS/SSL.

All settings are in Set up a mail app.
