Use these settings to connect TrekMail to any email app (Outlook, Apple Mail, Thunderbird, etc.).
Who this is for
- Users configuring a desktop or mobile email client.
- Developers configuring a script to send email.
1. Incoming Mail (IMAP)
Use these settings to receive email.
| Setting | Value |
|---|---|
| Server Hostname | imap.trekmail.net |
| Port | 993 |
| Encryption/Security | SSL or SSL/TLS |
| Username | Your full email address (e.g., alice@example.com) |
| Password | Your mailbox password |
Note: We do not support POP3 (which deletes mail from the server). Please use IMAP to keep your email synced across devices.
2. Outgoing Mail (SMTP)
Use these settings to send email.
| Setting | Value |
|---|---|
| Server Hostname | smtp.trekmail.net |
| Port | 465 (Recommended) or 587 |
| Encryption | SSL/TLS (for 465) or STARTTLS (for 587) |
| Username | Your full email address |
| Password | Your mailbox password |
| Authentication | Required ("Password" or "Normal") |
Important Notes
- Username: Always use the full email address. Just
alicewill fail. - Passwords: Use the specific mailbox password you set when creating the user, not your TrekMail account password.
- App Passwords: We do not require specific "App Passwords". Use your standard mailbox password.
- Free Plan Sending: If you are on the Free plan, you must configure "Bring Your Own SMTP" in the dashboard for outbound mail to work, OR use your external provider's SMTP settings directly in your client (e.g., SendGrid's SMTP).
