Anyone else having a problem with their spamd-protected mail servers being unable to receive mail from a number of mail services due to them immediately giving up on a 451 error?
I've definitely had a problem with AOL doing this, and I've managed to white list them, but I'm getting reports from a fair number of people that are having the same problem from seemingly other servers -- I send them a 451 and they toss up their arms and immediately quit trying and bounce the message back to the sender. And yes, the bounce message is funny -- clearly saying the mailer gave up on what is clearly being described as a "temporary failure". My mail server is passing every test I can think to toss at it, spamd seems to be working perfectly, and I can't come up with a configuration error on my end that would explain an immediate fail on a temporary error message...and yet I haven't found other references to this problem elsewhere, which seems an odd combination Anyone else experiencing this? Nick.
