My message <4C7433C6.50705 at seichter.de> was all about this question: is
it sufficient to allow rw access to the user "dovecot", or does every
user who connects via IMAP need to write to the dict socket. I'm sorry
if I did not make this clear enough.

Anyway, I call dovecot-lda as Postfix's mailbox_command, so I understand
that the socket needs to be world-writeable? I read the Wiki pages for
Dict and Expunge, but did not find them conclusive. You have the unfair
advantage of having written the software and thus knowing exactly how it
behaves. ;-)

Yes, the Wiki states that "Even without this plugin it's possible to use
doveadm to expunge messages". Howevery, I don't think the Wiki currently
mentions that "doveadm expunge -u" (in contrast to "-A") does not use
the expire plugin's data at all?

Of course, I believe you if you tell me that there is no point in using
the expire plugin in my particular scenario. I shall disable it.
