Are you using the -f or -d flags to procmail? I see that those will cause procmail to add a mbox header if one does not exist. I assume that since people have been using rcvstore with procmail for a long time that you should NOT use that when using rcvstore. If you are not using those flags then something above procmail is generating that. I confess that I do know if it is standard to have programs called from a forward file to receive an mbox-formatted message or not! Since rcvstore is designed to be called from a forward file, I think that maybe the standard is to NOT receive a mbox-formatted message. I also see that procmailex(5) shows an example of using formail(1) to filter out and regenerate 'From ' headers, and it is looks trivial to use it to just filter it out. Unfortuntely, ">From" escaping in email bodies is not reversable, so the only good option is to not have the final delivery agent generate those escapes. --Ken -- nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers
