Hi,

I also use spamassassin/procmail to treat spams.  However, I feel that SA 
does not scan for viruses.  Am I wrong?  That is why I am looking for a
virus-scanner.  I found that many virus-scaning packages strongly
recommend sendmail with milter support, and mention that sendmail without 
milter is "old".   That is why I originally post this question here:  I
install the sendmail on fc1, but did not see any reference about milter.  
Is sendmail without milter really old?  where can I get milter for
sendmail on fc1? or no way?

Scot, the url link you provided is very useful.  I did it similar, but I
will improve my setting.
A few questions, see *** below.  Please help.

Thanks!

A couple of things I did differently was to add a rule in procmail to
flag a message when it went through so spamassassin did not get run
against the same message twice.  
  *** Could you tell me what rule do you add to avoid "twice scan"? 

Also to have a single bayseian database
I invoked spamc with the -u option to specify a dedicated user
(spamuser) so the database is kept under that users home directory. 
  *** what is spamuser? a special user you set for spamassassin?  I don't 
see this point in spamassassin doc.  Could you explain it more? 

The only other thing you need to know is that the bayseian database
rules are not applied until you have run several hundred spam and ham
messages through it.  The easiest way to do that is to use sa-learn to
process known spam and ham which you can collect from yours or other
users accounts.  
  *** This will be a more general "strange question".  Most of my users
don't know how to run ssh to connect to our email server.  The only thing 
they know is to use pop3 mail tool (Netscape mail, Outlook express, etc.) 
to read/send emails (I don't blam them, they are experts in other
fields).  To my undersdanding, each user needs to run sa-learn to let
his/her own bayseian database learn about spam and non-spam (different
users may have different opinion:  I do have 2 users asking me just
completely opposit qustion about the same mail.  One said this mail
should be blocked, while the other saked why this mail is marked as
"spam").  If the users don't know how to run ssh (I disabled telnet), how 
can they run sa-learn?  Is there any way that the system admin (root,
superuser) can run sa-learn for other users, i.e. to make their bayseian
database learn about "their" spam and non-spam?


This has worked very well.  In the last few weeks there has been a
tremendous increase in spam, I think due to several worms that have hit
the net.  

Suggest at first you move all spam to a holding area so you can review
it to make sure you do not see any false positives.  I did not see any
real problems with that here but it is better to be safe about it.
