Icedove spots at least 80% of those. Out of the ~180 'DATA' commands I received yesterday, 83 resulted in an SMTP- time rejection, 8 were forwarded to SpamCop. My site-wide settings are quite conservative. >I refuse a (by now) >quite large collection of CIDR blocks. Of the ones that resulted in an SMTP-time rejection, most were from a mail server that has poor SPAM-scanning, but that shouldn't be rejected at the firewall. Since IP != identity, I'm not willing to block any ip address or range unless I have a mechanism for automatically expiring those blocks. However, spamassassin accesses some half-dozen free-to-use DNSBLs that serve the same purpose. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
