A few of our exchange IPs get blocked intermittently, but only by ATT. Ips =
are clean, no issues, we=E2=80=99re diligent about finding and fixing these=
types of issues as it has a large impact.
It would be very helpful to know why the IP below got blocked so we can fin=
d and fix the problem to prevent further listing. We have a few ips in rota=
tion and some have no issue. It=E2=80=99s a =E2=80=9Cblind=E2=80=9D listing=
, so we only find out about it when customers complain that they getting bl=
ocked.
