Connect IONOS (1&1)
IONOS email over IMAP and SMTP, with the password of the email address. Works
| Signs in with | Mailbox password |
|---|---|
| Username | Your full email address |
| Incoming (IMAP) | imap.ionos.com, port 993 (SSL/TLS) |
| Outgoing (SMTP) | smtp.ionos.com, port 465 (SSL/TLS) or 587 (STARTTLS) |
Each email address has its own password. These are the servers on IONOS's US help pages; accounts on other IONOS country sites may use a different server name.
