I already use MainScanner with ClamAV and F-prot, Spamassassin, and they are great. However, my problem is not with the delivery of mail, it is with accessing IMAP. That is the only service creating such heavy loads. It was suggested I move to maildir, that seems to be the predominant opinion. I wil try to migrate a test setup to maildir and if the migration is successful, do it on the main server. Thanks for the advice, I have found the MailScanner list people very knowledgeable and I did not think to ask them for advice. Chris Mason -- No virus found in this outgoing message.
