Maybe you need no re-think the requirement to scan at SMTP time. I also prefer that, but statistical scanning is so much more powerful than anything else that I finally gave up on SMTP scanning and moved to delivery-agent scanning, just so I could use statistical methods. Ham/Spam reporting is done by forwarding false positives/negatives to a special address. Is there a particular reason that you need SMTP scanning? That being said, Cyrus fits the bill for everything you want except the mbox requirement. But, there are plenty of scripts around that can migrate mbox onto an IMAP server, so that's not necessarily a showstopper. Cyrus 2.1 works just fine with Squirrelmail, and it supports shared folders with full ACLs. Plus, after you move your mbox messages into the Cyrus message store, they're available from anywhere. I personally hate mbox; it's slow, especially for large mailboxes (the uw-imap trick of putting a fake "index" message at the top is an ugly hack); its format is brittle (the >From escape is another ugly hack); it's dangerous (better hope everything accessing the mbox is using - and honoring - the same locking scheme). Did I mention that it's slow yet? -- Dave Carrigan Seattle, WA, USA [EMAIL PROTECTED] | http://www.rudedog.org/ | ICQ:161669680 UNIX-Apache-Perl-Linux-Firewalls-LDAP-C-C++-DNS-PalmOS-PostgreSQL-MySQL
