I am running sendmail that comes with Red Hat 8. We require managing email POP accounts for lots of domains belonging to our clients. As such, I have placed the entries for users into the /etc/mail/virtusertable file. I have then run a makemap hash virtusertable.db < virtusertable and restarted sendmail.
All user accounts have been created using the Red hat User Manager (GUI).
So, if I have the following user accounts
and also add the following into /etc/mail/virtusertable
All of the mail for the domain foo.com comes to foo_rob? I even tried adding the following entry at the end of virtusertable
@foo.com error:nouser User address is not valid
If I send an email to firstname.lastname@example.org
even though this account does not exist it comes to email@example.com
!!! There is nothing in the aliases pointing to foo_rob and I am using the default sendmail.cf
Has anybody seen anything like this before?
