Hi Folks, I've spent most of this week on this and am just getting frustrated. I'm Sysadmin for an ISP. I installed MIMEDefang, Spamassassin and filter::scan on my Red Hat Sendmail server as a way of dealing with my customers spam/virus (mostly the spam, it's a REAL problem).
As far as I can tell, MIMEDefang/Spamassassin are working OK. I tested Spamassassin when I installed it with the sample-nonspam.txt and sample-spam.txt included. Mimeddefang adds this header to e-mail: X-Scanned-By: MIMEDefang 2.48 on 127.0.0.1 and Spamassassin adds a SpamAssassinReport.txt as an attachment to each spam mail. But I've been reading websites for two days now and can't figure out how to do anything else with this. Basically I don't want spam coming into my users mailboxes, they don't want it. I understand there will be some amount of false positives, but I just want to drop (or bounce or whatever) the spam before it reaches the mailboxes. I'ld also like to drop, bounce, whatever mail that has certain words in the subject, such as rolex, penis, viagra, etc. I know I can do the above with MIMEDefang/Spamassassin, but I'll be darned if I can figure out how. And the more I try to figure it out, it seems, the more confused I am getting. Also, I'm not sure how I'm supposed to feed it spam. I have Sendmail/Qpopper and most of my users pick up their mail using Outlook Express. I understand I can't just forward spam to a spam mailbox and run sa-learn on that as the forwarding will not get the original headers. There has to be a easy way to learn to use this and get it to do what I want but I can't really figure it out. Surely there are some other ISP's on these lists who might be willing to tell me how they use it. Thanks, Lisa Casey
