Hi Phil,

Basically just used zmprov to turn off all the virus/spam/attachment scanning in zimbra.  Now amavis doesn't even start :)  Next was just install MailScanner and Julian's clamav/spamassassin installer as I've had problems with the Zimbra-ised versions of these during upgrades of Zimbra.

I haven't bothered looking into a zimlet for MailScanner although that sounds like a damn good idea - happy to be a beta tester.  As for the MailScanner config, I just left it all in the files, but if I were running a multi-server setup, I'd probably look at storing the config in LDAP (it was supported many eons ago in MailScanner - not sure if Jules kept it though).

I still use all the zimbra LDAP/Postfix/IMAP/POP3 fru-fru, but I haven't found an elegant way yet to pick up the mail users identify as ham/spam.  All I've done is told them to forward it to ham/spam at ....  Plug in a quick-and-dirty shell script that uses fetchmail and sa-learn, add it to a cron job and voila.  Fit for purpose, but damn ugly.

Cheers,

James
