Please help with IP Address Blocking
We are a web-hosting company and are having problems sending emails to a client of us with a sbcglobal.net email address, from 2 different email addresses and two different IPs
host al-ip4-mx-vip1.prodigy.net [144.160.235.143]
SMTP error from remote mail server after MAIL FROM::
553 5.3.0 alph165 DNSBL:ATTRBL 521< 188.138.17.243 >_is_blocked.For assistance forward this email to @abuse-att.net
Same happens when sending emails from another IP - 188.138.9.196
We have very strict policies against spam and restrict a lot our customers from sending newsletters, so there should be no reason for being blacklisted... we are not on any RBL
Would you please unblock those 2 IPs for us, 188.138.17.243 and 188.138.9.196?
We would appreciate that since need to regularly contact our customer at an sbcglobal.net email address
Pls advise

Hello, @Harpwro
We understand how much of a hassle this could be. You would need to reach out to report your complaint to abuse@att.net, Someone will get back to you in help get your IP addresses unblocked. Charles, AT&T Community Specialist
