Hello, I get the following error in /var/log/mail.err when attempt to send an email to myself from squirrelmail. I followed the ISPConfig 3 perfect server install but am still having issues with email. Any help would be much appreciated. In addition every time I create a new mailbox in ISPConfig I get a "failed to connect to IMAP server", with permission errors.
