We solved our Spam / Virus issues and mail load on our filers by installing a pair Spam/Virus firewalls in front of our mail cluster. The product is by a company call Barracuda Networks www.barracudanetworks.com. It's really simple to setup and works well with exchange. With this setup the spam/virus firewall scans for spam & viruses and then forwards the message to our mail cluster.
Best regards,
Blake Folgner

My experience has been that a netapp (F840, ~1/2T in my case) has no problem at all with 200,000+ mailboxes. Postfix for the MTA, Maildir delivery. We utilize a cluster of FreeBSD (4.9) systems, about 10 systems for smtp delivery, and 3 systems for imap.
The slowest thing that I deal with in my mail system is the time it takes to filter the email for spam/virii.
Question: can you share (in general) what you use to filter spam/virii? Were they in place the same or before the Netapp deployment?
I'm figuring out if stopping mail from hitting the Netapp in the first place (discard spam and virus mails at the MTA level e.g. via sendmail-milter+dnsbl+amavisd+clamav) will greatly help alleviate filer performance woes.. and hopefully get some actual figures of "before" & "after" stats..
Thanks all who have responded so far: it helped me (perhaps others too) greatly.. :)
