No. The expire plugin is just doing some unnecessary extra work here and
logging that. I fixed in hg so that it now instead logs:

expire: Iterating only a single user, ignoring expire database

If you don't use -u or -A then it tries to access the current system
user's mails.

I improved this error message now in hg to show what user doesn't have
access.

doveadm tries to access the expire database via the dict socket. You
didn't really give enough information about what user you're running
doveadm as or if you're using system or virtual users or..
