Well, since it's not actually bouncing and just being deferred, that's not too bad at least. It does seem to fail often enough however and I've been ripping my hair out trying to figure out why. I do have MX, SPF and RDNS records for everything. Yet, I keep getting things like; To Yahoo, delivery 239: deferral: Connected_to_209.191.118.103_but_greeting_failed./Remote_host_said:_ 421_Message_from_(x.x.x.250)_temporarily_deferred_-_4.16.50._ Please_refer_to_http://help.yahoo.com/help/us/mail/defer/defer-06.html/ delivery 244: deferral: Connected_to_216.39.53.3_but_greeting_failed./Remote_host_said:_ 421_Message_from_(x.x.x.250)_temporarily_deferred_-_4.16.50._ Please_refer_to_http://help.yahoo.com/help/us/mail/defer/defer-06.html/ delivery 248: deferral: Connected_to_216.39.53.1_but_greeting_failed./Remote_host_said:_ 421_Message_from_(x.x.x.250)_temporarily_deferred_-_4.16.50._ Please_refer_to_http://help.yahoo.com/help/us/mail/defer/defer-06.html/ delivery 259: deferral: Connected_to_206.190.53.191_but_greeting_failed./Remote_host_said:_ 421_Message_from_(x.x.x.250)_temporarily_deferred_-_4.16.50._ Please_refer_to_http://help.yahoo.com/help/us/mail/defer/defer-06.html/ To Hotmail; delivery 236: deferral: Connected_to_64.233.163.27_but_connection_died._(#4.4.2)/ Gmail messages and hotmail don't even show up at all and no bounces either.
