Mail-Rules for IMAP-Server?


ich sync my calendar and contacts via nextcloud for my PC, Laptop, iPhone and iPad. That works fine.

My several IMAP-postboxes would be filtered by Outlook on the PC with a lot of rules to move mails in different subfolders. On all devices I use Outlook. Thats ok so far, but when the PC is offline, for instance on holidays, I have on the mobile devices all mails in the inbox without filtering. Thats very bad. OulookMobile and Mail on IOS has no filter possibility. So I look for a solution on my nextcloud, which is on a RaspberryPI allways on, to filter the postboxes on the IMAP-Server.

Is there any solution for that?

Best regards
