Advice Please - Virtual Users And Domains With Postfix, Courier, MySQL, SQMail Ubuntu

[TomT]

Hi

Currently my Mail Server is Mercury32 on a Windows 2003 Server, with ClamAv, SpamHalter, Content and Transaction Filtering.

I've followed this HowTo :
http://www.howtoforge.com/virtual-us...ail-ubuntu8.10

and now have Postfix, Courier, MySQL, SquirrelMail, SMTP-AUTH, TLS , Quota, Amavisd, SpamAssassin and ClamAV installed.

All went quite well apart from 2 typo's from me
I've installed this in a virtual Ubuntu 8.10 desktop edition.

I'm currently waiting for DNS entries to update on an old domain I have to test this properly, but things are looking OK at the moment.

Seems to be working well, but I have a couple of questions..

1. How do I tell if ClamAV is up to date ? How do I get FreshClam to update daily.

2. Can I add more DNSBL entries to either PostFix or SpamAssassin ?

3. Is it possible to block hosts who don't have properly formed domain name in the ehlo/helo ? But have a couple of exceptions (for family) ?

4. Is there any way to have the system move 'spam' or potential spam to another user for checking through later ?

5. Any way to monitor all the logs in a simpler way ? using System Log shows lots of info, but most of it is mixed in with other entries.

Thanks

AFAIK freshclam is updating daily. I think you can configure this in freshclam.conf.

Take a look here: http://www.howtoforge.com/block_spam..._level_postfix
I'm not sure if exceptions are possible.

You can specify a quarantine user in the amavisd configuration.

The mail logs are in /var/log/mail.log.

Thanks for the reply.

Do you know where the default locations for clam.conf / freshclam.conf are ??

Also where amavisd conf is ?

Thanks again.

[TomT]

I've found the conf files thanks.

Quick question is this setup using clamav or clamd ?

How easy would it be to make it use clamd ?

I've installed SafeSquid and that can use clamd as well.
Thanks

It's using clamd.

[TomT]

Ahh.. #

How can I tell what port it is running on ?

Also is there anyway to get more logging output from amavis-new or clamd ?

Whilst I'm testing this it would be nice to see a lot more detail on anything that has been scanned and/or blocked.

Just need to work out how to add the exceptions to Postfix.. Hopefully that can be done.

Thanks

I'm not sure if you can put amavisd and/or clamd in debugging mode. If it is possible, there should be something mentioned about it in the configuration files.

[TomT]

Thanks for the reply.

How do I check clamd is running ?
doing netstat -tap doesn't show any ports in use by clamd !!

Try
