qmail user information (user deleted)
 

Dear all,
I am facing a big problem, this is 3rd time user of my office complaint me that he can not access his e-mail account, when I checked his email account there was no account with his name, also there is no folder in domain folder for the same user.
I am administrator/ Postmaster of my Domain and I did not delete his account then where is his account and how can I find who did this ?? is there is any log or way to find when this user account deleted, who did this and how???

please help me in this problem.

Thanks in Advance.

Are these local users or virtual users? Who all has access to the machine? Does anyone else have admin or root password?

all users are virtual (qmail server users- email users) no one have root/ admin password.
is there is any log to see any detail.???
