[courier-users] Rejection/re-insertion methodology howto?
Hi, I am now fighting my way through configuring courier-mta with virus and spam filtering and I must admit I lack some good documentation for that. I have read about the rejection/re-insertion metodology and would like to ask you if you could enlighten me about it a little bit more. As far as I understand it, its' a method where courier accepts an email on one port (25) then forwards it to a global filtering program. This program then makes any tests necessary and (if the message is ok) re-sends the message to courier to another port. Is that correct? Could anyone show me a functional example, please?

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 If the queue docs on courier-mta.org are close but a bit out of date (I don't see /any/ mention of global filtering there) I'm sure many of us would appreciate an update somehwere.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...

Hmm - that's interesting. Really could use more documentation to this topic (scheme, more about the filters). A Howto would be excellent. ;) Regards, David.
