As title states.
I didn't have any trouble before, but we started having problems with emails being sent to @sbcglobal.net email accounts. Here is the error that happens:
reason: 553 5.3.0 flpd239 DNSBL:ATTRBL 521< removed IP >_is_blocked.__For_information_see_http://att.net/blocks
Is there a fix for this? Checked the blocked addresses in the mail options and it is clear.
