Cloudron email 'social' and 'promotion' filters?

[christiaan]

My last email host (Dreamhost) has the option of filtering emails not only into 'spam' but into 'social' and 'promotion' folders too. It's a really nice feature.

Does Cloudron have this?

No, but it would be nice. What’d be really interesting though is the ability to create domain-wide email filters.

@christiaan Did you have to setup the filters manually for filtering or did they have something pre-setup for this?

This is indeed a good idea! It's easy to create the folders atleast but the filtering rules might be the hard part. I wonder if it's easy to write sieve filters for this.

Replying to myself: https://www.infomaniak.com/en/support/faq/1729/workspace-automatically-filtering-incoming-emails-sieve-filters uses the List-Unsubscribe header . Not sure how 'standard' that is.

All preset. Here's what the anti-spam option looks like in the Dreamhost control panel:

On my hunting around over the past few weeks trying different hosts, I noticed another host was providing this exact filtering but I forget who it was now.

Here's Dreamhost's technical details on filtering. They use Vade Secure to scan incoming and Procmail as the 'delivery agent for the mailbox which actually places the email into Spam, Social or Promotions folders when it detects the Vade Secure headers'

Just my personal opinion and might be unpopular, but I think this ultimately should be up to the users to setup their own filtering as they desire. Because that's all this is, it's just pre-set filters when you come down to it. It's easy enough for users to make their own. I think the time of the Cloudron developers are probably better spent elsewhere.

Yeah, like @d19dotca I am not 100% sure if we can put this in Cloudron itself (yet). But for a start, if anyone has any helpful sieve filters, I can put this in our docs. For example like https://github.com/deependhulla/promotionsmailtagging seems to use SA to place a header and then moves it using a sieve script. Strangely, I couldn't find any other work in this direction already. (I am looking for a well-maintained sieve filter archive).

From what I can see, these services use Vade Secure, which is probably the most advanced independent (not Google or Microsoft) email filtering system.

There is basically no way for Cloudron to have filters as good as these, without contracting Vade Secure and paying hundreds / thousands of dollars in licences per instance...

Geez, I see, I thought Dreamhost did a good job of filtering my email!

[yusf]

What if we had Cloudron instances cooperating by contributing data to a decentralized email filtering algorithm, somehow without sacrificing privacy…?

@christiaan You can manually setup filters in SOGo, Rainloop, Roundcube, etc in Cloudron to do the exact same thing here. I can assist in a PM if you would like help setting this up.
