    Thank you for your input. SpamAssassin quarantines messages based on certain scoring. Although you can tweak these settings, if you have DNSBL configured your emails get rejected before they reach SpamAssassin. The problem here is with the reject policy of postfix. As far as I am aware those policies are not as flexible as one might want and it is fairly complicated to configure. If you have any suggestion on achieving this particular goal, we would love to hear it. Thank you in advance.

    3 and a half days in second week after some additional adjustments in my 'custom.cf'-file results in 0 spams in inbox and 0 false positives. This happens with all usecases (also my problem child usecase 3). Therefore this is a huge improvement.

    And I want to emphasize, this edit is in configuration of spamassassin, which may be connected with amavis daemon and similar, but has nothing to do with configuration of MTA's like postfix.

    Plesk just has to have the right to write new files or modify created files in /etc/mail/spamassassin/ . All text files with ending '.cf' are obeyed if at least a part of content is good (command 'spamassassin --lint' tells which section is wrong).

    Details how to do this manually I wrote in https://talk.plesk.com/threads/possible-to-use-dnsbls-for-moving-identified-email-as-spam-to-spam-folder-not-blocking.375318/post-951518 . I will have to update it as my little updating of 'custom.cf' and adjustment of scorings have made usecase 2 and 3 at least that good like usecase 1 (or better but I did not test long enough).

    If one has access to the server, one may use 'dnsbl' for helping in scoring messages by spamassassin. So these dnsbl's do not block without informing but move emails recognized as spam to the spam folder. If the email was ham and therefore a false positive, the user can move this email back to inbox or a subfolder not containing spams. Then perhaps plesk automatically trains spamassassin that this is not spam or one can integrate this action in a cron job.

    Also hugely important: As I and other customers have many emails in other languages, for example spamhaus (URIBL_DBL_SPAM) produces many false positives. Bad is that as default spamassassin uses spamhaus.org as helper. After manually reducing the spam score, I and my customers have no false positives anymore.

    How I manually have done it, is described here: https://talk.plesk.com/threads/possible-to-use-dnsbls-for-moving-identified-email-as-spam-to-spam-folder-not-blocking.375318/post-951518

    FTPS with websitename.tld works using Let's Encrypt. So enough security is possible if wished. But nevertheless it would be great if something like ftp.websitename.tld would be possible with a guilty Let's Encrypt certificate.

    And take in account: One can enforce users to use guilty secured connection. Then only websitename.tld is possible with FTPS.

    It would be really, really, really ... did I forget "really"? Well, then I repeat ... it would be REALLY nice this feature would be implemented after about 6 years.

    At least I would like to know what is technically hindering for implementing this.

    Hey @"Kaspar", look at the date it was initiated. In earlier times with IMAP one could remove virtually emails, but physically they stayed in the inbox. I took the workaround using POP3, so messages are downloaded and then really the mail server courier or other (not dovecot!) deleted the messages physically (not only virtually!). Why this problem existed, I do not now. Nowadays with IMAP one can delete emails and they are deleted physically on server, too.

    But nonetheless tanks for the short explanations as nowadays surely the most users with plesk run postfix with dovecot (as it seems to be the default now when installing a new internet host with web- & emailservice).

    Oh, implementing push notification for ios devices devices does not seem to be easy, but it would be really great if this or something similar can be implemented.
