Hello,
Is it possible to force a certain user to use SMTP AUTH while allowing others to use both SMTP AUTH and POPB4SMTP?
I would hate to turn POPB4SMTP off server-wide, but we are having a problem with one of our clients who denies sending SPAM mails and says that his IP address is shared with other people (NAT) and he shouldn't be hold responsible.
