Pkg exim4 users - Oct 2008 - Antivirus and Antispam

Hi,

I''m installing a pc with debin 4.0 and exim4, I want to add antispam
and
antivirus protection, which packages are actually doing the best with it?

In my last installation I used sa-exim and clamav-daemon packages... but 
time passed and I want know if they still are the good ones...

TIA

sa-exim is not needed, you can use spamassassin using the exim''s acl
other options less resource intensive like dspam or crm111 should be
used instead of sa

clamav is also included in the acl, but the clamav-daemon i think still
is a good idea.

I use ASSP, http://www.asspsmtp.org/wiki/Welcome
It works very well. Make sure your spam filter has at least bayesian 
filtering, and grey listing, with grey listing being the first check, as 
it stops 90+% of all spam and is cheap in CPU and bandwidth usage. In 
fact once I turned on grey listing my spam went down from about 20 a 
week to 0 a week.

I never really found dedicated virus filtering to be very effective, 
since viruses will be filtered out by other means anyways.

Does it works with fetchmail? 
I''m asking it, because I cannot control the mail server, it''s
from my isp, and
I download the mail using fetchmail, so, I don''t know how to
incorporate this
kind of filters.

Hi,

I''m configuring a new installation of Exim4, and I want to enable DNS
Black
list verification, I see the next lines in the file exim4.conf.template

  .ifdef CHECK_RCPT_IP_DNSBLS
  warn
    message = X-Warning: $sender_host_address is listed at $dnslist_domain 
($dnslist_value: $dnslist_text)
    log_message = $sender_host_address is listed at $dnslist_domain 
($dnslist_value: $dnslist_text)
    dnslists = CHECK_RCPT_IP_DNSBLS
  .endif


But I don''t find the definition of CHECK_RCPT_IP_DNSBLS anywhere on the
file
not even commented, it''s defined in a different file?
Should I insert the definition on exim4.conf.template?
Or Should I do a different thing to make it work?

TIA

Jesus Gutierrez

Hello,

if you don''t use "split config", yes, add it in top of 
"exim4.conf.template".

Otherwise create a new file in /etc/exim4/conf.d/main and add it in this 
file.

I am running  spamassassin and a clamassassin script using procmail. This 
works between fetchmail and exim4

I am sure it would work with fetchmail. Just tell fetchmail to pass the 
fetched email to ASSP''s port, ASSP in turn will pass it to the local
MTA
to be delivered to the mailboxes.

Let''s say you have ASSP listening at 127.0.0.1:25, then you configure 
ASSP to send email to, for example, 127.0.0.1:26 (SMTP Destination). 
Your MTA is configured to listen on 127.0.0.1:26 and will take care of 
delivery.

I have trying to configure it this morning but it stopped me because in their 
web page they say:

Who is it not for? 
...
 Domains which receive mail indirectly.
 Fetchmail for example.
