dovecot - Aug 2007 - UIDL match from 0.99.13 to 1.0-1.2

I am moving from and old FC2 system to a new RHEL5 system and am having
trouble getting the UIDLs to move over right, mainly the UID.

I copy over the mailbox, and see the x-uid in the message is what it was
on the old server, but when I telnet in to check pop, it rewrites x-uid
in the message to something new, causing old messages to get downloaded
again, which is not what we want

I have tried setting pop3_reuse_xuidl to yes, but that did not change
anything, probably because that is the wrong header (I do not have
x-uidl, but I do have x-uid).  I do have pop3_uidl_format set to %v.%u
for compatibility.

On the old system the first five are:

+OK Logged in.
uidl
+OK
1 1095087961.3092736
2 1095087961.3092737
3 1095087961.3092738
4 1095087961.3092739
5 1095087961.3092740

On the new system the first five are:

+OK Logged in.
uidl
+OK
1 1095087961.3093018
2 1095087961.3093155
3 1095087961.3093156
4 1095087961.3093157
5 1095087961.3093158


Any help would be appreciated, I do not understand how it is generating
the UID portion.

Then there's something in those headers that causes Dovecot to decide
that they're wrong and they need to be rewritten. The rules have changed
a bit since 0.99.

One thing I can think of is: Does the first message have X-UID: header
before X-IMAPbase: header?

Why, yes, it does.  Do I need to swap them ore delete X-IMAPbase, and is
there a utility to do that, or do I have to make one?
