I've read (somewhere, can't remember where) that using ERROR is better than REJECT in /etc/mail/access. Use lines like this: # domains you don't ever want to get email from -- REJECTS ENTIRE DOMAIN @21cn.com ERROR:"550 Too much spam" # reject specific email address Financial_Freedom_Awaits11 at yahoo.com ERROR:"550 Too much spam" sendmail has support for RBLs. see cf/README in the sendmail source. As far as rejecting on key words in headers, you're probably better off implementing spamassassin or something similar.

This is on an SCO Openserver 5.0.6 box. > I am just having some problems setting exceptions for any accounts such as: AOL, Yahoo, Hotmail when the domains are set to REJECT later in the file. And secondly i am wondering if there is a way i can add subject line checks to the file and reject on keywords in the email subject line, ;ike in the Postfix regular expression header-checks? _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list
