I think it's urgent to set up a spamfilter on Wikimedia mail server. A lot of spams are sent.
List admins have to clean the list queue, and it has become a burden.
I am proposing the configuration below. This do NOT need any additional server ressources.
It simply blocks invalid addresses and virus.
mime_header_checks = regexp:/etc/postfix/mime_header_checks
Additionally, these services could be used to prevent more spams.
I use them since 2 years.
Earlier proposed configuration:
I strongly advise against using the rbl_client rejection Even those who publish
the blackhole lists (like spamcom.net) advise against using them for rejection
instead of flagging. They tend to be quite aggressive and generate too many
false positives. The problem is that in most cases the user never finds out
My ISP uses such techniques and when I found out that they were rejecting valid
e-mails intended for me because some bozo reported a sourceforge mail server to
an rbl, and I couldn't even sign up because the sign-up verification message to
me was being rejected. I couldn't convince my ISP that 1) it was blocking
legitimate e-mail or 2) that this was a bad thing to do even though spamcop's
policy pages say so.
The best use of rbl's is as one symptom in a spam filter, not for outright
a subset of these rules are now implemented. RBLs are not used in postfix.
mail is also run through clamav and spamassassin.
