[Dovecot] UIDL match from 0.99.13 to 1.0-1.2

[Daniel Davidson]

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.
