You need sendmail or some other mail transfer agent. procmail isn't an MTA. Once you decide on the MTA then I suggest you look at using spmassassin to filter out spam. It works great! If you decide on sendmail or exim then add on MailScanner. MailScanner integrates seamlessly with sendmail and will work with over a dozen commercial virus scan engines. The cheapest of these is F-Prot which is excellent and they only charge by server not be the number of users. they also provide their scanner free for home use. I'm not aware of any open source virus scan engines that are kept up to date in the same manner as the commerical ones??? By the way, MailScanner has it's own built in spam filter but works best with spamassassin. I use this setup at on my home system (sendmail, MailScanner, F-Prot, and spamassassin). The packages were simple to install and setup. No changes were required for sendmail out of the box from Redhat. -- Gerry "The lyfe so short, the craft so long to learne" Chaucer -- redhat-list mailing list unsubscribe mailto:redhat-list-request@;redhat.com?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
