Thanks for your quick answer. It sounds so interesting.

May I ask you how many users do you have, and have do you allow your users
to change their passwords? I'm wondering how do you handle so many users
(expiration, adding/deleting users or domains and so on) with password
files. Actually I need MySQL because of the billing system, that's possible
I'd also have to create scripts if I use different password files. Tell
you the truth I'd use MySQL because the web management also.

Okey, what do you think about the security of exim?
