ok, i did setup a test, and these are the results ;)

sh-4.3# doveadm search -u luuk savedbefore 2d
6e076801a027c655aa700000e4766c2b 1
a11f76379f27c655a4700000e4766c2b 1

sh-4.3# doveadm expunge -u luuk mailbox INBOX savedbefore 2d
sh-4.3# doveadm search -u luuk savedbefore 2d
6e076801a027c655aa700000e4766c2b 1
sh-4.3# doveadm fetch -u luuk mailbox savedbefore 2d | sed 's/^L//g'
mailbox: Sent

sh-4.3# doveadm expunge -u luuk mailbox '*' savedbefore 2d
sh-4.3# doveadm fetch -u luuk mailbox savedbefore 2d | sed 's/^L//g'
sh-4.3# doveadm search -u luuk savedbefore 2d
sh-4.3#

doveadm -D expunge -u user at domain mailbox '*' savedbefore 2d
