I was having a tidy-up of my Debian install last night and trying to sort out some sort of spam filtering. To access mail I simply use Sylpheed as a straight dial-up POP3 client. I don't use procmail, sendmail or any sort of MTA (or at least I don't think I do :o) ). So I did a apropos search on 'mail' and came up with a long list of things that had been installed as part of the base install. Given they way I access my email can I uninstall things like procmail, sendmail, and various MTAs? or is this likely to break something else? I'm thinking of using 'mailfilter' (mainly because it can act as a POP3 client) to scan the mail headers on the ISP server and delete any spam before I download it. Given my setup, are there any alternatives I should also look at? As part of setting up mailfilter I need to set up a set of regex entries to identify possible spam. I'm reasonably happy with regex itself but if anyone has some anti-spam regexs I can crib I would be most grateful :o) What would be nice would be to use some of the DNS blacklist servers e.g. spamcop, ordb, etc., in some way, can I do this with this sort of configuration without actually downloading the headers 1st?
