Emails are not been saved/received I installed ISPConfig on Ubuntu Dapper. Everything looks good. I can connect to the server, send emails (which arrive at the receiver) or check for new emails. Problem is that incoming mails are not being received or saved. /var/log/mail.log doesn't show an error. Is there another log file that could lead to the problem? I'm using Maildir by the way. Thanks for your help!
Because this error occurred only with a few mailboxes I deleted and recreated them in ISPConfig. Now it works.
