I'm running sme v6 and having lots of trouble trying to control spam even though I have spamassan installed. Behind the sme is an exchange 2000 server. I seem to get a lot of mail with the address postmaster@my.domain. How can i stop this, it's choking up the exchange queue.Any help would be appreciated.

Here are some ideas for you to research.

1. First and most important, turn off any notices other than to 'admin' do not send messages to sender or recipient, they are more than likely spoofed addresses anyways.

2. Then find the contrib to reject unknown users.
dmc-mitel-mailrules-0.0.1-7.noarch.rpm

3. Install clamav and filter out virus messages.
pagefault.org Install their virus contrib

4. Find the contrib that denies viruses at the smtp level.
e-smith-email-4.14.0-07gr1.noarch.rpm
e-smith-mailfront-1.5.0-13gr03.noarch.rpm
mailfront-0.91-3es.i386.rpm

Make sure you READ what these do and how to fix them if they destroy your system. I have had no problems with any of these but you may have other results. Setup a test system and use that to add these in and make sure they work as advertised.

Also, anything you can find that blocks at the SMTP level is preferred because of the speed increase of not having to open a message to check for viruses using perl. Contribs for numbers 2 and 4 block at the SMTP level, which is nice.

Hope that helps,

Jon

One more thing. :)

Those packages I put in there may have been updated since I installed my server so look for updates to them. And with updates sometimes come problems, make sure you test them before you put them on a production box.
