IMAP & SMTP
Your mail app
still works.
Standard IMAP and SMTP over SSL are on every plan, so Apple Mail, Outlook, Thunderbird or your phone connects in a minute. The webmail is there when you want it — it's just not the only way in.
Included on every plan. See all features.
Add your mailbox to any client:
- Server
- mail.supermailos.com
- IMAP
- 993 · SSL/TLS
- SMTP
- 465 · SSL/TLS
- Username
- you@yourdomain.com
- Password
- your app password
Step-by-step in connect a mail app.
Standard protocols, no lock-in
No proprietary sync, no forced webmail — just the standards every mail client already speaks:
IMAP over SSL (993)
Your mailboxes sync over standard IMAP with implicit TLS, so read, unread and folder state stay in step across every device you use.
SMTP over SSL (465)
Send through standard SMTP with implicit TLS. Mail you send from a desktop or phone client is still DKIM-signed and authenticated on the way out.
On every plan
IMAP and SMTP are included on both Pro and Business, for every mailbox and every alias. There is no tier where you're locked into webmail only.
App passwords
Mail apps sign in with a separate, revocable app password rather than your login — so two-factor stays on your account and you can cut off one device without touching the rest.
Works in every client
Apple Mail, Outlook, Thunderbird, iOS and Android Mail — anything that speaks standard IMAP/SMTP connects with the same host and ports.
Webmail is optional
The full threaded webmail — search, labels, drafts, signatures, keyboard shortcuts — is there when you want it, but it's a choice, not a cage.
IMAP & SMTP questions, answered.
Incoming mail uses IMAP on mail.supermailos.com, port 993, SSL/TLS. Outgoing mail uses SMTP on mail.supermailos.com, port 465, SSL/TLS. Your username is your full email address, and the password is an app password you generate in your security settings.
