Do you know if this change does not upset other implementations
of imap servers?

Mike, are you Ok with this change?

I only tested it with cyrus 2.1.18 on debian. I did some research: The 
From_ header field was introduced in rfc976 which only affects UUCP(Unix 
to Unix CoPy). I assume it's an invalid header field in SMTP/IMAP, and 
most implementation ignores it.
I'm no mail header guru, so I could be wrong

Thanks; then will apply.

By the way, Markus, did you send the patch with imap-send?  It
had a funny whitespace corruptions.

No, I was too lazy to set up an imap config for one patch. So I used git 
diff an copy pasted it into Thunderbird. Sorry.

Works for me with Courier IMAP.  I'm no expert on mail headers either, 
so no objections from me.
