Situation: latest ISPConfig, VPS with Fedora core 2, sendmail/pop3. Problem: Sendmail handles mail for 'user' normal when mail is addressed to webn_user@site, but mail to user@site gets refused by sendmail with 'user unknown' errror. Both 'webn_user' and 'user' feature in '/etc/mail/virtusertable'. But in '/etc/passwd' features only webn_user. Perhaps that has something to do with it. How can I cure this from ISPConfig ?
