Hi and TIA,

I have been working on this little problem for a few weeks now and need some help before i go completely nuts.

I installed a new mail server, oss zimbra suite, it does its job of sending and recieving BUT, the attachment filtering options are not the best, its only allow or deny options for everyone at once. That is a problem because i have different departments on the company (about 100 people total) some can recieve ALL attachements, others, cant recieve any, others, can recieve some. so the solution would be to either have some sort of group policy or at least per user policy.

Even though its based on oss software, its not the orginal version of them, so hacking those could be troublesome, and would prevent from an easier upgrade process in the future.

At one point it was suggest that i do the mail filtering outside of the zimbra server and just forward the email to the zimbra server. I belive thats is now the best option i have at this point, even though i dont like to have two mail servers to do the function of what i belive should be a single mail server.

So, I need a mail server that can filter attachments on a per user basis, and while i have searched the net, googled, chatted in irc channels and other forums, i had overlooked this one. So I hope someone can enlighten my path with some good ideas and sugestions.

Some things i have to keep in mind, easy of use, mail routing, mx records priority, backup.

Any ideas are apreciated.

For nomral MTA such as Postfix you can use procmail to filter out emails. But, I'm not sure if this will work with zimbra.

However, you can use procmail from another user using IMAP.

You need to setup something as follows:
