Postfix on Mandriva Gateway for Exchange

[gregnottage]

Hi,

I'm running Mandriva 2008 One and I've attempted to follow this how-to guide:

http://www.howtoforge.com/mandriva_p...virus_exchange

I'm trying to configure Postfix to scan inbound and outbound smtp mail on my network. We use Exchange 2003 internally on a Windows 2003 domain. I also have an ISA firewall sat at the border, so the Mandriva machine is behind this ISA box.

I have email flowing just fine without using the Mandriva box. So when I have Exchange setup to route external SMTP through the ISA server using the IP of the ISA server as a smarthost, it all works fine inbound and outbound.

As soon as I set the smarthost IP on the Exchange server to point to the Mandriva machine, email stops flowing.

I'm a total newb with Linux, so please be gentle

I don't even know where to look on the Mandriva box to see if mail is being received into any of the queues?

I have tried telnetting to the Mandriva box using port 25, and I think it connects - I don't see any message saying it couldn't establish a connection - but I also don't see what I would class as an SMTP connected notice?

I have disabled the firewall on the Mandriva box - as a temporary measure, to see if that made a difference but unfortunately it hasn't so far.

Any help you can offer is greatly appreciated!!!

Thanks and kind regards,

Greg.

Hi Guys,

After a bit more digging around, I've found the following information contained in the Postfix logs:

The /var/log/mail/errors.log file was empty

I assume that this means the config is not quite right yet?

Any advice based on the above logfile contents is greatly appreciated!

Thanks and kind regards,

Greg.

OK, I've fixed all those errors and I'm making some progress

It now appears as though my problem lies with Amavisd. Having Googled for this, I should be able to telnet to 127.0.01 on port 10025 - but this is not working. I've tried to amend the amavisd.conf file and now when I issue the command amavisd reload, I get the following error:

The amavisd daemon is apparently not running, no PID file /var/lib/amavis/amavisd.pid

Any ideas why that's occurring and how I should fix it? Should I just re-install Amavisd and start over?

Thanks,

Greg.

OK, I did manage to get Amavisd to run now after using the amavisd debug command and fixing what was wrong there. I can telnet to 127.0.0.1 10025, but it seems like the email relaying is not configured correctly. I now get the following error in the /var/log/mail/info/log file:

Any ideas what needs changing?
