Hello, For the record, SORBS once blocked our mail server due to a spam bounce generated when our spam filter discarded a message. We had to turn off all such bounces, so now senders who send mail which is classified by mistake as spam don't get any warning and their mail is silently discarded.
As far as I know, SORBS blocked us on a *single* evidence of such a bounce. Here is what the admin of SORBS wrote me: > Your server is sending spam to the email addresses forged by viruses or spam. > As > virtually 100% of spam and viruses are sent with a forged From address, your > messages > do nothing but harass someone who had nothing to do with the spam. > See > http://www.spamcop.net/fom-serve/cache/329.html and > http://www.spamhaus.org/faq/answers.lasso?section=ISP%20Spam%20Issues#109 > Please let us know when you have disabled such messages and we will be happy > to delist > your IP.
