I have a user who's sending an email to three addresses in another domain. The messages remained queued, and never get sent. When I check the queues, I see the following message:
The connection was dropped by the remote host.
I have verified with the sender that we are not blacklisted, that they are not using ReverseDNS......and here's the real kicker, I can send to their IT person without issue.
Nothing in my logs indicates there's an issue. I just sent an email to the three addresses in question, and as of right now, two people have verified receipt of these emails.
