for the past few months i’ve had spamassassin setup to send just about everything to my “caughtspam” file expect what i had specifically whitelisted, as seen here from my spamassassin local.cf file:<\/p>\n

whitelist_from *sears.com
\nwhitelist_from *plaind.com
\n****snip my whitelist is long****<\/p>\n

header SUBJ_BC895 Subject =~ \/BC895\/
\ndescribe SUBJ_BC895 Catch bearcat subjects
\nscore SUBJ_BC895 -100 <\/p>\n<\/blockquote>\n

\nthis example will also show you how to filter via spamassassin based on subjects, in this case, from my bearcat scanner yahoo group.\n<\/p>\n

\nbut, i figured i could just do this with procmail and not have to worry about “scoring emails” at all, just send everything to my caughtspam file except what i have specifically sent to my inbox. so my first procmailrc file looked like this:<\/p>\n

\n

\n:0
\n * ? formail -x”From” -x”From:” -x”Sender:” \\
\n -x”Reply-To:” -x”Return-Path:” -x”To:” \\
\n | egrep -is -f \/home\/vim\/whitelist
\n\/var\/spool\/mail\/vim<\/p>\n

:0:
\n* ^Subject:.*\\BC895\\
\n\/var\/spool\/mail\/vim<\/p>\n

:0:
\n* ^Subject:.*\\blog @ nightmare.org\\
\n\/var\/spool\/mail\/vim<\/p>\n

:0
\n\/home\/vim\/caughtspam\n<\/p>\n<\/blockquote>\n

but that still let spam into my inbox (because anything to: vim at nightmare.org would get through) and i only wanted to filter on who it was from, not who it was to. so i changed the filtering bit at the top thusly:<\/p>\n

\n

\n:0
\n * ? formail -x”From” -x”From:” -x”Sender:” \\
\n | egrep -is -f \/home\/vim\/whitelist
\n\/var\/spool\/mail\/vim\n<\/p>\n<\/blockquote>\n

so now procmail checks for valid senders against my whitelist file: \/home\/vim\/whitelist and puts anything on the list in \/var\/spool\/mail\/vim and everything else in \/home\/vim\/caughtspam which i can check whenever i feel like it. i could have made a whitelist for subjects as well, but i’m only worried about subjects in two cases so i put them right in the procmailrc file.<\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"
