E-mail Error 553

look around

I am having on-going problems sending e-mails to some customers in the US. The latest one has an address @sbcglobal.net. The latest error message I received is

5.1.0 - Unknown address error 553-'5.3.0 flpd112 DNSBL:ATTRBL 521< 213.233.128.45 >_is_blocked.__For_information_see_http://att.net/blocks'

I have had the same problem with 2 other addresses with the same domain over the past month or so.

I use Vodafone Broadband.

Any ideas
:mad:

The clue is in the error message. The account you are using or the domain it is coming from is blacklisted on the receiving end and will not go through.
