Save the account

SSL on by default. iOS enables SSL/TLS on port 993 automatically when it verifies your IMAP settings. You shouldn't need to change anything in Advanced settings.

Verify and test

Open the Mail app. Your Topmail inbox should appear. Send a test message to yourself to confirm sending is working.

Troubleshooting

Cannot send email

Go to Settings → Mail → Accounts → [your account] → Account → Outgoing Mail Server → smtp.topmail.com → tap the server → check that port is 587 and SSL is enabled.

Password rejected during setup

Make sure you are entering your full email address as the username (e.g. yourname@example.com), not just the local part.

SSL certificate error

Go to Settings → Mail → Accounts → [your account] → Account → Advanced. Confirm "Use SSL" is toggled on and the server port is 993.

Emails not arriving

Check your device has an internet connection, then go to Settings → Mail → Accounts → Fetch New Data and set Push or a short fetch interval.
