It’s really straight forward, just set SM up to use auth. Updating Squirrelmail is pretty painless. Here’s mine: IMAP Settings -------------- 4. IMAP Server : mail.covisp.net 5. IMAP Port : 993 6. Authentication type : login 7. Secure IMAP (TLS) : TLS 8. Server software : dovecot 9. Delimiter : . and SMTP Settings ------------- 4. SMTP Server : mail.covisp.net 5. SMTP Port : 587 6. POP before SMTP : false 7. SMTP Authentication : plain (with IMAP username and password) 8. Secure SMTP (TLS) : STARTTLS 9. Header encryption key : > Also, I'd like to futureprooof my code.

You probably do not want http running on the machine that runs postfix. That machine should pretty much have only the mail ports and ssh open if possible. Also, Roundcube is faster and has more “golly wiz!” features that SM and will probably make your users happier. You might consider running ti side-by-side with SM. -- Good old Dame Fortune. You can _depend_ on her.
