[Dovecot] X-SAVEDATE & dync & doveadm expunge

31 Dec 2010


      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
