First of all thanks for a detailed response. The reason we wanted to go in the MTA and Zimbra is because we only wanted to manipulate mail that has already passed the virus/spam scan. We will be removing all attachments to a secure ftp place (or something like that) and placing a message in the mail notifying of where to get them. This is just a requirement.
I plan to use anomy and we were also thinking of adding MailScanner to boot. I admit I am a complete newb at postfix/amavisd and all. I had tried to figure out how to add our piece to the existing amavisd/postfix configuration but I am at a complete loss as to how things flow in relation to the config options you have to set to affect change.
At this point anomy requires a shell script to start a new process for each message. This is how they say to integrate it into postfix
mailbox_command = /usr/bin/procmail -a "$EXTENSION" -p /etc/procmailrc
what I lack is the knowlege of where this fits into the grand scheme of things. Does this happen after or before amavisd. Thus I was thinking of adding another postfix instance that I could tinker with and possibly add other scanners/filters as desired.
What I also do not know is if I can accomplish integrating anomy after amavisd. The way I think it works is that postfix sends mail to amavisd over a socket and then amavisd sends it back. Anomy is not daemonized yet so I would have to find a hook in amavisd to call out (maybe via procmail or other).
Please, even if you cannot completely answer, the more information you can provide the better I can understand and perhaps craft my own solution.
thanks
