Description Sönke Schwardt-Krummrich

2017-10-05 15:20:28 CEST

The cron job "univention-spamassassin" in /etc/cron.daily/, that calls 
univention-sa-learn on a daily basis, does not perform locking. Therefore customers with large mail spools will run into the problem, that the next instance of the daily learn job is started before the current one has finished its job (overlapping cron jobs).

There should be some kind of locking.

The behaviour hasnt changed in UCS 4.4.
A customer has noticed that univention-sa-learn is causing a significant daily load even in the early stage of a project where mailboxes have been deployed but the amount of messages and especially the not mentionable usage os Spam/Ham folders should not cause a load peak for over 8 hours. 
Beside the more generic question if a training based on spam/ham classification is still appropriate nowadays we should look if there is a better and scalable solution.
