Hi Till, Within ISPConfig 3.0.2, i created a Fetchmail account. After fetching the e-mails from an IMAP server succesfuly, i made the Fetchmail account non-active and after that i deleted it, because i did not need it anymore. Then it happened that i received 3 emails from MONIT which is installed on the server as well: Description: 'amavisd' failed protocol username [SMTP] at INET[localhost:10024] via TCP I think this is not normal and my question is can you reproduce that as well? Another reason can be that the > 500 mails i fetched caused an overload. Can i avoid this when i use Fetchmail?
