Virtual Users and Domains with Postfix ... (FC5)

As per following the HowTo, page 2, step 7: created the user and group "vmail". and also at page 5, step 14: Populate the Database ... and in there create the user [email protected], that's all I've done about [email protected]-account
* When I look into my "User Manager", I do have
User Name: glenn UID 500 GID: glenn
User Name: vmail UID 5000 GID: vmail
User Name: postmaster UID 5001 GID: postmaster
User Name: abuse UID: 5002 GID: abuse

* Those UID and GID, must they be the very same as for "vmail" system UID i.e. users that we added with "useradd" commands to /etc/passwd file?

* What more can I do to make sure about the existing account's?

 

I think the problem could be that glenn is a system user on your system instead of a virtual user. Maybe that confuses Postfix.

 

do you have any suggestions on what to do?

 

Try deleting the system user glenn.
