To be fair, very few mail servers I know of or have used have this feature.
At least Postfix and Sendmail have it. It's not that exotic. It should be fairly simple to add to Courier.
About all that needs to be done, AFAIK, is add a seek() to line 947 of submit2.C, or close the control files before run_filter and reopen them afterward. It doesn't look like the afx lib in use has a suitable seekp() function, so the latter may be easier than the former.
No -- the problem that prevents this from working is that by that time the message's MIME structure is already parsed. If, suddenly the message's contents change, the pre-parsed offsets of various MIME entities in the message will result in a corrupted message, should Courier choose to rewrite it.
