I'm thinking of rejecting connections from some 'spam problem areas' in
the connect acl.
Below are the config I wish to use.
Does anyone have anything to comment? Might I end up with some
unexpected problems? Are the regexes matching the end users and do their
ISP's really serve them with mail gateways?
Regards,
Andreas
