However in the .spamassassin file in you home directory you can set a level of spam stuff that is identified before spamassassin rules it is genuine spam. The defaut that come with the software is 5 and is too low. 5.5 is better. Thye higher the number the less spam will be identified. Spamassassin just identifies the spam by putting something like [SPAM} in the header. You need to use something like procmail to remove it from your mail automajically. A procmailrc like this: PATH=$HOME/bin:/usr/bin:/global/bin:/usr/ucb:/bin:/usr/local/bin: SHELL=/bin/sh MAILDIR = $HOME/Mail # You'd better make sure it exists #LOGFILE = $MAILDIR/procmail.log LOCKFILE= $HOME/.lockmail INCLUDERC=/etc/mail/spamassassin/spamassassin-default.rc :0 *^Subject:.*\[SPAM\] spamjunk Will remove all mail with [SPAM] in the header and put it in the file spamjunk in the Mail directory/ All this is configurable. -- ------------------------------------------- Aaron Konstam Computer Science Trinity University 715 Stadium Dr. San Antonio, TX 78212-7200 telephone: (210)-999-7484 email:akonstam@xxxxxxxxxxx
