Before this PR, in https://github.com/chatmail/relay/blob/1.7.0/cmdeploy/src/cmdeploy/dovecot/expunge.cron.j2 we execute a number of "find" commands, which at least on nine.testrun.org take overall 45+ minutes to complete, and access the full directory structure 9 times (kernel caching helps a little). The new
chatmaild.expirytraverses all mailboxes only once and has tests.On the server side, you can run "python -m chatmaild.expire /usr/local/lib/chatmail.ini" to see what it would remove. Only if you specify "--remove" will it actually remove it.
The PR adds also "python -m chatmaild.fsreport" which gives various statistics of file usages, last login times etc. This is not run in any cron job and purely for curiosity purposes (and to help determine what we might do if storage becomes full again).
