My ISP has been "blacklisted"!

other way round. see DUL

only the next tier fixed IP (and
that with a degree of intelligence). But many of the poorer quality
black list services don't check. So... if someone has ever dialed in or
gotten the IP we are currently using and has sent spam over it, AND if
someone receiving that spam complained to the blacklisters... bingo.
That IP address is listed as a no-no.


So you are relaying mail via a dynamic IP? You deserve to be blacklisted
(i.e.: that dynamic IPs are blacklisted).

In general we will never know it (we get no bounce mail or anything) -
until enough customers call about why we ever sent them that report we
promised or whatever.

do what has to be done: relay through your ISPs MTA or get a static IP with
a correct PTR.

Then it's track down who their ISP is, and TRY to
find out what blacklisting service they are using, then TRY to get SBC
(who does NOT consider us a major account G) to send a note to the
blacklister...

Royal pain, and a cure as bad or worse than the disease.
