I currently have both in use on my personal email, and I can't get any emails from a specific domain. I've checked the BoxTrapper queue and it's empty, so it's not that. I've also checked the SpamAssassin spam folder, so it's not there. The domain I can't get emails from is phpbuilder.com. I'm a moderator at a fairly active forum, so I kind of need the emails. I can't figure out why they're not being delivered, but other forums (RoundCube Forum, cPanel, Simple Machines) all are being received. Did I miss something in the setup? I've whitelisted the email address the mail comes from, and still nothing.
