Have you guys seen a 4.4.2 error but only from a specific sender? I am troubleshooting email where someone we send mail to we're receiving the 4.4.2 "lost connection" bounce.
1. We have only one recipient domain reporting they can't get email from us 2. Sending email to them from a GMAIL account simultaneously, they will receive the GMAIL one but not the other one The issue seems to be on their end (as the 4.4.2 would indicate, since we seem to be able to send to everyone else), but it seems odd that it's just from us and not Gmail at the same time. Ideas? Dave
