A few ideias that came to my mind:
- The Quarantine email tab as an option to check the email hearders spam score etc. Expand that option to the sent and received email tabs (omitting the body of the message if easier).
- Having the possibility to select an email in either of the 3 tabs and declare the email as spam or ham it would be very useful. Basically something along the lines of what MailScanner does with the MailWatch web interface.
- When realeasing an email having a text field to enter an alternate recipient for that email;
- Having the mail queue of postfix in the panel, similar to what webmin does;
- If possible parse the postfix, dovecot, amavis and other relevant software into a database so it can show in the iredamin panel.
