How to set autoexpunge rule for single user mailbox in dovecot conf?

[Aki Tuomi]

You can do

passdb {
  driver = passwd-file
  args =  /path/to/some/file
  skip = unauthenticated
}

and put in this file

alice at example.com::::::noauthenticate
userdb_namespace/inbox/mailbox/INBOX/autoexpunge=31d

or nopassword instead of noauthenticate.

Please keep replies in-list.
