[Dovecot] Bug: Fixed a duplicate

[Tom Sommer]

I restored a dovecot mailserver today, and when I started the server 
again, the logs filled up with "Fixed a duplicate" warnings.

This in itself it not a problem, the problem is that it appears the fix 
is not done correct. Consider this:

Warning: Fixed a duplicate: 
[X]/cur/1305907573.V807I37682f3M146183.mail8.xxx.com:2,S -> 
1306601066.M382668P27710.mail8.xxx.com

The problem appears to be the timestamp of this new file isn't updated 
correctly.

Now I got hundreds of mailboxes filled with mails named 1305907573.* 
with random (in the past) timestamps, leading to mangled miss-sorted 
inboxes for customers.

68850 May 25 00:46 1306600913.M983002P26976.mail8.xxx.com:2,S
etc.

Dovecot is v. 2.0.11

I guess I should have deleted all dovecot.* files after the restore, 
before I started dovecot?
