I can't give you a definitive answer, but I can tell you a little.
I first saw the above message when I was playing with the UW IMAP
server a few months ago.  And given the X-IMAP header, it seems
pretty obvious that they are related.

I believe (since I haven't examined the c-client code much)
that this is part of how Pine can set the Answered flaged on
postponed messages.  If you were to look at your mailbox
now, you'd note that Pine has started adding a couple more headers
to all of your messages.  One of them is an X-UID header, which I
assume Pine uses to find the message you were originally replying
to.

My guess is that the X-IMAP header in the message you've quoted
contains

  X-IMAP: 0900019774 0000000063
	  ---------- ----------
a timestamp   |		 |
			 |
a msg uid number --------|

I would guess the timestamp had something to do with the last
modification time on the folder, and the UID is the last message
UID given out.  For instance, in my mailbox the second number is
380 and the last message has X-UID: 380 ... coincidence?  I think
not :)

I don't know what else it's used for.  I would guess that
if you deleted at most you might find it annoying--pine4 
would recreate it, and any information you would have lost
would likely only be "annoying" and not serious :)

I hope this helped, somewhat.

I'm going away for a month.  How do I get off the forum so that my
mailbox doesn't over flow?

The wrong way is to post an off-topic message like this and annoy everyone on
the list. You didn't even bother to change the Subject!

The right way is to take a look at the headers and figure out which list server
is used. 

As you can see, it's ListProc. So, send a command to [email-masked].
Don't know what the commands are? Send a help command.

Commands are sent in the BODY of a message, only one per line left justified. 
Delete your .sig. Leave the Subject blank.

The command is

	set pine-info mail postpone

To resume

	set pine-info mail

To learn about the set command

	help set

See the Sender in the headers? That's the address of a person. If you have
trouble, contact the list owner at that address. Never post questions like this
to this or any other mailing list.
