[Dovecot] X-SAVEDATE & dync & doveadm expunge

[e-frog]

Hello List,

After moving the mail store via dsync backup to a different location the 
following command
	
	doveadm expunge -u user mailbox "Trash" savedbefore 10d

deleted ALL mails in Trash instead of messages older than 10 days.

It looks like X-SAVEDATE is somehow wrong...

A fetch 1:* (internaldate x-savedate)
* 1 FETCH (INTERNALDATE "28-Dec-2007 14:49:58 +0100" X-SAVEDATE 
"01-Jan-1970 01:00:00 +0100")
A OK Fetch completed.

...while the ctime for this mail is as below:

$ ls -lac
-rw------- 1 vmail vmail  40851 2010-12-30 19:26 
1198963359.P1256Q0M253583.ubuntu-test.localdomain,S=40851:2,S

I was assuming that for the maildirs X-SAVEDATE is derived from the 
message ctime? "01-Jan-1970 01:00:00 +0100" seem to be definitely wrong.

Thanks,
e-frog
