Postfix is unable to send mail to one domain. Mail to any other domain is delivered without issue. Here's the error: 2D444C98266: to=<[email protected]>, relay=none, delay=203441, delays=203350/90/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to mx.ps1.us.army.mil[143.69.251.34]: Connection timed out) These are emails sent through vBulletin to the registered member's US Army mailbox. Is the Army blocking me or do I have a misconfiguration in Postfix or vBulletin?
That's what I suspected... I'll ask the members who have US Army email addresses to see what they can do to get the block removed.
