Re: mail antivirus

Mircea,

1) DSPAM - very effective, it learns what is spam and what is not and  
continues to learn so it adapts to different styles of spam. Learning  
is very fast and false positives are virtually nil (in fact I can't  
remember the last time I had one - I'm talking many months, if not  
years). I have arranged for spam to be automatically moved to a  
separate 'Junk'  folder on an IMAP server based on DSPAM's  
classification using a simple sieve script. However I still monitor  
the junk folder just in case, but it's hardly worth it and I could  
probably simply delete these mails.

2) SQLGrey - (not actually a SPAM filter, I use it front of and in- 
conjunction with DSPAM). Highly effective and as unobtrusive as a  
greylisting solution can be. Occasionally annoying having to wait a  
few minutes for emails from a new source (eg site registration  
emails), but the number of spams that simply get dropped, makes it  
very worthwhile.

I now get approximately 15  spam emails a day (as opposed to 200 a  
day) and these are mostly to postmaster, hostmaster, webmaster, etc  
RFC addresses to my domains. Only the occasional spam is to my real  
email address and this address I have used for over 10 years and  
posted to usenet, mailing lists and used for pretty much everything  
(i.e. I've not been overly careful with it).

Hope that helps,

Steve
