There are many "dirty" ways and a few "clean" ways. The clean ways I know of: 1. transport_filter (spec chapter 24, towards the end) on the local delivery transport 2. a custom transport with a pipe driver, where the pipe command is a script involving spamc 3. set up .forward files for users and leave it to them not to break it :) You should also look at the content scanning features and at the malware control on ACLs. While the primary use of ACLs is at SMTP reception time you _can_ run an arbitrary ACL from an expansion in a transport stanza. This is what Jeremy suggested in a recent thread I started, and I have done that and it works. That said I haven't found the malware control very convenient to use. -- Please don't Cc: me privately on mailing lists and Usenet, if you also post the followup to the list or newsgroup.
