Evidently, the 'doveadm expunge' command requires a "mailbox" to be defined in the search string.
But is there a way tell it all mailboxes for a user? For example, something like:
doveadm expunge -u user@domain mailbox ALL savedbefore 30d
Thanks,
Michael

just like the example thats here: http://wiki2.dovecot.org/Tools/Doveadm/SearchQuery
doveadm expunge -u <user> mailbox '*' savedbefore 30d
That doesn't work for me either. The command is accepted, but the messages are not expunged.
I guess my search/fetch will just have to return the mailbox name, in addition to other fields, and then I'll need to loop through the mailbox names and perform multiple expunges for each user. I understand the desire to avoid accidents by requiring that the mailbox be specified. But if "mailbox ALL" or "mailbox '*' were allowed, that would still avoid the accident and yet also avoid the inefficiency of having to perform multiple expunges for one user.
*** Enhancement request: provide a "mailbox all" or "mailbox '*'" option for doveadm search_query so that expunge can be used to remove mail without regard to which mailbox it's in.
Are you sure you really want to do this? My server expunges Trash and Junk on a cycle, but reaching into other mailboxes seems iffy.
Yes. I understand it's unusual. This is an RF (radio) application for emergency services. We have to be efficient about channel utilization. Users know they need to keep their mailboxes clean so that, at the start of an emergency (or other incident), the channel is not clogged with downloading lots of old, irrelevant mail. If they haven't logged in for a while, we'll keep it clear for them.

How i read the docs here: http://wiki2.dovecot.org/Tools/Doveadm/SearchQuery and here: http://wiki2.dovecot.org/Tools/Doveadm/Expunge
Is what i can test, but i will/can not test 'expunge' ...

After this, i think this should work: daveadm expunge ALL before 1800d
or, in you case: doveadm expunge -u <user> ALL savedbefore 30d
if this is not working, that this might be a bug?

Huh, it certainly did for me, although I used "all" instead of "savedbefore 30d" since I just wanted to empty the trash. What version of Dovecot? Mine is 2.2.27.
I guess that's reasonable for a critical application, but normally I would expect an IMAP client to request headers-only, or just recent messages. My phone's K9 client defaults to something like 2 weeks.

Well, not for me. doveadm search -u user@domain ALL savedbefore 2d -- returns some messages doveadm expunge -u user@domain mailbox '*' savedbefore 2d -- nothing shown, but no error doveadm search -u user@domain ALL savedbefore 2d -- returns the same messages as before
I've got 2.2.9 (Ubuntu package for 14.04)
Right. But your phone has 100s of kbps or even Mbps of bandwidth, full duplex. But when multiple users are sharing a simplex 56kbps radio channel, even just the headers of old/irrelevant mail are to be avoided.

The inefficiency of compiling a list of folders and expunging from each single one seems quite minor to me. That is, as it seems, when "expunge" search-query requires a real mailbox/folder name.
Maybe you can "doveadm move" selected messages to a /fresh/ folder and then expunge that one completely? Slightly less efficient, easier to script though all the time.

maybe the debug option '-D' gives a clue why it failes on your site?
doveadm -D expunge -u user@domain mailbox '*' savedbefore 2d

doveadm -D expunge -u user@domain mailbox '*' savedbefore 2d
I don't see any errors in the debug output. And if there was an error, one would expect to see an error message when running the expunge command even without debugging turned on.
Thanks for trying. I've got to put this aside for a few days to meet a deadline for another project. I'll pick it up with more testing after that.
