Hi,
What is todays most effective combination to filter spam ?
On my old Redhat 3 system I used Sendmail and Spamassasin .. it was good, but with the current setup we are getting way to much spam.
Looking around I found new players, well some I did not know then and they are very interesting..
MailScanner .. http://www.mailscanner.info/ Sagator .. http://www.salstar.sk/sagator/ Smf .. http://smfs.sourceforge.net/index.html dspam .. http://dspam.nuclearelephant.com/index.shtml
I am tempted to go with smfs because it is familiar .. but, mailscanner seems popular
I've been very happy using the RBLs with Sendmail. In sendmail.mc add:
dnl # dnl # dnsbl - DNS based Blackhole List/Black List/Rejection list dnl # See http://www.sendmail.org/m4/features.html#dnsbl dnl # FEATURE(`dnsbl', `bl.spamcop.net', `"Spam blocked see: http://spamcop.net/bl.shtml?%22$&%7Bclient_addr%7D%27)dnl FEATURE(`dnsbl', `cbl.abuseat.org', `"Spam blocked see: http://cbl.abuseat.org/lookup.cgi?ip=%22$&%7Bclient_addr%7D%27)dnl FEATURE(`dnsbl', `sbl.spamhaus.org', `"Spam blocked see: http://spamhaus.org/query/bl?ip=%22$&%7Bclient_addr%7D%27)dnl FEATURE(`dnsbl', `list.dsbl.org', `"Spam blocked see: http://dsbl.org/listing?%22$&%7Bclient_addr%7D%27)dnl FEATURE(`dnsbl',`dnsbl.sorbs.net',`"554 Spam blocked " $&{client_addr} " found in dnsbl.sorbs.net"')dnl dnl #
