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 ?
Is your sendmail configured that it uses /etc/mail/virtusertable properly? Thats OK. In /etc/password are only the usernames stored.
Super, thanks for quick reply. Turned out that virtusertable did not get updated into virtusertable.db. Thought that happens automatically when sendmail is started but apparently not. ran a 'make -C /etc/mail' and now they work as they should ! schoenen gruss !
