Greg,
I appreciate your initiative to reduce the email spam on this list. I
understand that spam is at >least annoying, but sometimes even dangerous when viruses are conveyed. Of course, an >effective countermeasure is required, that is also simple to use.
While I'm not a mailing list expert and do not know about the particular
constraint of this list, >my understanding is, that posting a message to this list now would become a 2 stage process. >This could counter the spam but at the price of user friendliness <SNIP>

Greg,
A simple answer to remove most of your spam at server level is to use some of many good blackhole lists that verify open (insecure) relays, and qualified spam senders then put them in a DNS type list that your mail server can query. If your using sendmail then you can just add the following into your sendmail.mc: FEATURE(dnsbl, `blackholes.mail-abuse.org', `"550 Mail from " $&{client_addr} " rejected, see http://mail-abu se.org/cgi-bin/lookup?" $&{client_addr}') FEATURE(dnsbl, `relays.mail-abuse.org', `"550 Mail from " $&{client_addr} " rejected; see http://mail-abuse.o rg/cgi-bin/nph-rss?" $&{client_addr}') FEATURE(dnsbl, `dialups.mail-abuse.org', `"550 Mail from dial-up rejected; see http://mail-abuse.org/dul/endu ser.htm"')
