Block spammer using IMAP

Question

Is it possible to block a sender as spam using imap (by the wonderful MailKit api), in any way?

Currently I'm just moving these spam mails in a specific folder, but this doesn't prevent emails from the same sender to sent another mail.

I know it is possible in the mail client, to "flag as spam", but I'm not sure what's happening "behind the wall".

The IMAP protocol does not support such an action. What most mail clients do is implement their own client-side IMAP message filtering.

So if you want to implement a spam filtering, then you have to add and maintain a blocker addresslist on you own, I guess? – grmihel Nov 19 '15 at 15:22
correct, you'll need to implement custom logic for tracking blocked addresses and logic to move those messages (if/when found) to another folder or marking them as spam or whatever your client wants to do with them. – jstedfast Nov 19 '15 at 17:06
