Dave Crocker asked:
Do you see multiple message-id's in messages?
I don't recall seeing any, but then I've not be looking so it
might take more than a few for me to take notice.
If you do, what affect do they have?
However, if I _did_, my Message Disposition Notification
generator parses headers from the top down so that earlier
message-ids would replace any later ids for the
| DO WHILE LINES(msg_file) > 0 & hdr > ""
| PARSE VALUE hdr WITH hdr ':' value
| hdr = TRANSLATE(hdr)
| WHEN hdr = "MESSAGE-ID" THEN msg_id = STRIP(value)
| WHEN hdr = "DATE" THEN msg_date = STRIP(value)
If this is normally the way headers are parsed, then normally
later message-ids would be ignored.
