I don't think that's quite right. IIRC, it goes like this (I'm probably wrong): submit creates the control and data files in the "temp" queue. These are named in such a way that courierd doesn't pay attention to them. Then, "filtering" takes place. Note that one end of submit is still talking to the "sender" (let's say esmtpd) and the other end is the filtering stuff. That's how (I think) the filtering messages get back to the smtp dialog. I'm probably way off base here. Anyway, after filtering is done, submit renames the control and data files and signals courierd, and exits. Mr. Sam: could you please give us a detailed "process overview" as to how messages go from (say, esmtpd) through submit, through the global filters, and then the final signaling of courierd? If the queue docs on courier-mta.org are close but a bit out of date (I don't see /any/ mention of global filtering there) I'm sure many of us would appreciate an update somehwere. I am willing to help out, but I need some pointers as to /where/ in the process filtering happens, and which files are responsible. Also, a reason why courier can't allow the modification of messages in global filters would be cool, and if you could point us to the source files relevant to that area I'm sure we'd all appreciate it. -- Ensign Walnut approaches Dr. Crusher with caution...
