Announce: more blacklist in use at mail.gna.org

Item posted by Mathieu Roy <yeupou> on Wed Jun 8 09:50:14 2005.

Considering a recent spam increase, we had to take action to make sure that spam filtering would not exhaust our servers. One option would have to limit (or even suppress) spam filtering, that would have caused more spam to be delivered by our servers. The other option was to limit incoming spam before our mail server accept to deliver it, called refusal at smtp time.

We picked the second option because we do not want to resign ourselves to deliver lot of spam.

Indeed, it means that it increases chances to block legitimate mails. However, the blacklist we added are open relay servers blacklists filled by "trusted users". It should prevent too many legitimates mails to be blocked.

We are aware there is currently a Free/Proxad SMTP blacklisted, apparently because a "trusted users" made a mistake a tested a server of it's own customer (that legitimately accepted it's mail). We have contacted both Free/Proxad and people running the blacklist so this issue get sorted out. Do not hesitate to post a support request if you have similar problems, we will do our best to address it.

Note that it's quite easy of a GNU/Linux user to run it's own SMTP (not accepting mails from the outside!), to avoid such troubles.
