Hi Shachar,
Both Spamhaus and SORBS are *not* listing IP's on the basis of bounces,
only on the basis of actual spam received, which happens occasionally,
despite the generally good policing efforts that gmail and yahoo do.
BTW, Baruch Siach also configured our main server (sendmail) not to relay
out bounce messages from our clients' servers that relay out to the world
through us since these are about 99% spam bounces. Configuration available
upon request.

Hi Shachar,
Spamhaus and SORBS routinely list yahoo, google, hotmail, tiscali and
other freemail addresses. So the problem isn't just SpamCop.
The main question is WHY they are being blocked.
Spamcop has been leading a crusade to make bouncing of incoming messages
a blacklist offense. I see this practice as abusive of Internet
protocols, and is inherently punishes any large scale SMTP operator
(ISPs included). The best I can do to fight this, however, is to
recommend to everyone not to use such brain-dead black hole operators.
If Spamhause and SORBS also adopted this foul habit, they should be
dropped too. Black listing someone for following the SMTP protocol is
not something that should be tolerated, and its effect on the mail
validity will likely be worse than that of spam.
Secondly, talking with ISP's is a waste of time,
Yes, that part of my mail was mostly wishful thinking.
I manage this problem on the TkOS mail servers by overriding the SORBS
and SpamHaus blocks for yahoo, gmail, hotmail, etc.
This may have solved your problem as far as receiving mail from those
specific servers, but did nothing to alleviate my original reservation
from SpamCop's service, that of punishing anyone who does not follow a
procedure made up by a closed comity, without any care or consideration
for proper standards and internet protocols, not to mention public
criticism.
Again, I don't know whether Spamhause and SORBS have the same problem.
If they do, however, your false positive rate has far greater problems
than merely gmail, yahoo and hotmail. Since you are running a server for
internal consumption, that is your prerogative to decide you don't care
about this problem. An ISP, however, does not have that prerogative, IMHO.
