I'm looking for help from what I assume to the Yahoo mail team - our
Mailing List server at 64.142.105.165 (lists.sonic.net) is being blocked
by the following servers:
al-ip4-mx-vip1.prodigy.net
al-ip4-mx-vip2.prodigy.net
ff-ip4-mx-vip1.prodigy.net
ff-ip4-mx-vip2.prodigy.net
Here is an example log line from our sendmail instance:
Jun 6 17:33:49 listman.sonic.net sendmail[30018]: 4570XhGQ029645:
to=<redac...@pacbell.net>, delay=00:00:01, xdelay=00:00:01,
mailer=esmtp, pri=211884, relay=ff-ip4-mx-vip2.prodigy.net.

64.142.105.165 >_is_blocked.For assistance forward this error to
abuse_...@abuse-att.net, stat=Data format error
Our same customer has reported this issue on May 8th and May 21st, so
this is the third time I have had to request removal of a block. Each
time, a consultation of the Spamhaus lookup service did not show our IP
address on any RBL.
If someone on this list can please reach out to me directly, I'd like to
get an explanation as to why we keep getting blocked and what we can do
to fix any outstanding problems.
