Allow Thunderbird to block senders at Server side

[gbolcer]

Feature request: Allow IMAP account to not only mark an email as spam, add sender to IMAP blocklist too. 

I have an IMAP account to Google I (am required to) manage in my Thunderbird client.  99/100 emails are simply commercial solicitations.  I can mark them as spam in the client and they get correctly marked as spam on the server. 

The issue is, a lot of these emails recently are obnoxiously persistent, where you get an email saying 'we want to talk to you about this topic...' and then as soon as an hour later you get a followup email 'We just wanted to followup from our last email...' and then maybe 4 or 5 different stages of followups over the next day or week and even a month later.  

The way I handle this is, I have to jump out of Thunderbird, launch a Web browser, log into the email account, and then both mark as spam and block the sender.   As I get dozens of these as well as nagging-aggressive followups, it's worth my time to block the senders.

This would be possible with client and server cooperation using such standards sieve and imapsieve.

However, a necessary first step in your case is for Google (gmail) to extend their support of one of the above standards.I don't see an public plans that they would do so. You'd have to ask them about that.

There however imap servers that do support these standards.  And such user control would be a great addition to Thunderbird.  But this is not currently on Thunderbird roadmaps.
