22.7 Legacy Series / Re: Having trouble configuring Firewall to allow Mail Server Access

Very rarely. Usually services/applications use a randomised source port. In some cases you might be able to specify the source port. In other caes (eg active ftp) that's the standard behaviour. As part of that you might want to lock down your firewall rules further and limit the source port on the rule.
