I am 100% sure that ATT wireless doesn't do this. That would be an incredibly strange (and non-standard) behavior anyway. Sounds a bit far fetched. I would start at the beginning. Have you eliminated smtp as the cause of the issue? Are your MX records up to snuff (and RFC). Does your mail server recieve any attempted deliveries from ATT? Would you care to send the full text of the undeliverable message (scrubbed)? This isn't entirely a FreeBSD issue, so if folks want to move this off list I'll give you a hand anyway. -- Benjamin Krueger "Life is far too important a thing ever to talk seriously about." - Oscar Wilde (1854 - 1900) ---------------------------------------------------------------- Send mail w/ subject 'send public key' or query for (0x251A4B18) Fingerprint = A642 F299 C1C1 C828 F186 A851 CFF0 7711 251A 4B18 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
