Hello, i am running debian (stable) for many years now as my email server (postfix/dovecot) with roundcube. that works like a charm but i was looking for some caldav/carddav integration, so i thought i test nextcloud.
after installing it and using cron for the cron.php, i noticed that some emails are flagged as important, which should not because they are not. even test emails suddenly were flagged as important. so i disabled the nextcloud site in apache and thought at least the tagging stops now. but it did not so i assume its a cron.php problem and found some other tickets that this was indeed once a problem, but seems like it got solved.
so i created emails are tagged as important which should not · Issue #9188 · nextcloud/mail · GitHub where i was told to disable cron. the guide says i should use cron, now a dev tells me i should disable it.
can someone please clarify wth is going on here and what is correct. for me this is a killer and something like this should never be in a regression. lucky me i received only about 25 emails in that time.
edit: i received now all the information.
nextcloud uses some sort of machine learning to label emails (Nextcloud Mail introduces Machine Learning for Priority Inbox while protecting your privacy - Nextcloud)
imho: this is so very wrong to have that enabled by default.
imagine someone who receives 100+ messages per day and all are labeled as important… the sender should decide whats important. if there is some special feature in nc that labels them for the receiver as important, this should only be done in nextcloud and only be visible in nextcloud, not manipulating the original messages.
