Creating similar mail-addresses causes problems

Hi guys,

I'm sorry but I've no time to test the following problem with the current trunk.

I'm running ispCP 1.0.0 and observed this:

I've a mail account, foo-bar@…, working. Now I create a forwarder foo.bar@… -> something@…. When I know send a mail to foo-bar, I get

550 5.1.1 < foo-bar@… >: Recipient address rejected: User unknown in virtual mailbox table

When I change let the foo-bar be re-configured (by changing the password i.e.), the problem disappears.

I think there's a problem with handling the . in foo.bar, maybe there's a regular expression, so - is matched; I don't know, but I'd be glad if there's someone to have a look at this.

Thanks & Bye
FeG
