Connect Any Email Account with IMAP
Not every mailbox is a Gmail or an iCloud. Maybe you have email through your web host, a cPanel account, an office server, or a smaller provider. As long as it offers IMAP — and almost all of them do — you can connect it to TrekMail and read and send from it in one place. You'll just enter the server details yourself, since there's no ready-made preset for every host in the world.
What you'll need
Gather four things from your provider (usually on a "mail client setup," "IMAP settings," or "connect your device" help page):
- The IMAP server name — often something like
mail.yourdomain.comorimap.yourhost.com. - The SMTP server name for sending — frequently the same host, e.g.
smtp.yourhost.com. - Your username — usually your full email address, occasionally just the part before the @.
- Your mailbox password. Most independent hosts use your normal password (no app password needed).
Add it in TrekMail
- In TrekMail webmail, click your profile picture (top-right) → Settings → Connected accounts → Connect an account.
- Type the email address, then open the Server settings section to enter the details yourself.
- For incoming, enter the IMAP server and choose the port:
993with SSL (most common), or143with STARTTLS. - For outgoing, enter the SMTP server and pick
465with SSL or587with STARTTLS. - If your username isn't the full email address, type it in the username field. Enter the password, click Test connection, and Save once it passes.
Encryption and certificates
TrekMail always connects over an encrypted connection — plain, unencrypted mail isn't allowed, for your safety. If your server uses a self-signed or mismatched certificate (common on small in-house servers), you'll see an option to trust that server's certificate; enabling it pins that exact certificate so the connection stays secure, and you'll be warned if it ever changes unexpectedly. If you're not sure, ask your provider whether they use a standard certificate — most do, and then there's nothing to configure.
If it won't connect
Double-check the server names for typos — they're the most common culprit. If receiving works but sending fails, swap the SMTP port between 465 and 587; some networks block one of them. If the login is rejected, confirm whether the username should be the full address or just the local part, since hosts differ. Your provider's own "email setup" page is the definitive source for these values. More tips in Fixing connected account problems.
