Anyone else noticed that in the last couple of days their e-mail to US are being blocked?
I keep getting back reports like:

<xxxxx@sbcglobal.net>: host sbcmx4.prodigy.net[207.115.20.23] said: 553
5.3.0 flpi112 – mABHOJZ1016728, DNSBL:521< 203.161.124.51
>_is_blocked.__For_information_see_http://att.net/blocks (in reply to MAIL
FROM command)

or

<xxxxx@sbcglobal.net>: host sbcmx6.prodigy.net[207.115.36.20] said: 553 5.3.0
nlpi078 – mAC1POFr012709, DNSBL:521< 203.161.124.51
>_is_blocked.__For_information_see_http://att.net/blocks (in reply to MAIL
FROM command)

i confirmed this by sending a test to an att address

521 <0.0.0.0> is blocked

The sending system has been identified as a source of spam.

Please see http://www.att.net/general-info/521.html for more infomation

it would seem that amcom has managed to get itself blacklisted on spamhaus, or one of many other spam filtering projects/services

i was able to send ok from my own domain, it is hosted within the us
have also sent from a @xxx.wa.gov.au domain ok

so this is an issue with amcom being blacklisted

hope that helps

Yep – the admins had nothing better to do that day but to work on getting the mail server black listed – lol

I would say a customer has either been infected with a bot/virus/trojan or one of the co-lo customers has been 'emailing all their customers' again.

whether that was now the case or not
i did have the same problem sending from my amnet account also the other night when testing that

But it would be nice to have the Amnet do something after few weeks to have themselves taken off the AT&T black list. AT&T are the major provider in US and we are prevented to send e-mail there. There surely are business customers who are suffering too.

Did you log a call or send an email about it?
