add a spam filter to webmail.vivaldi.net

[WildEnte]

To my knowledge, Vivaldi's webmail is a Roundcube implementation. As far as I can tell it does not have a spam filter integrated, be it learning or using external lists, so the Junk folder is "dumb". Vivaldi M3 Mail also doesn't have a learning filter. So if you stay within the Vivaldi Ecosystem, you don't have a lot of options when it comes to dealing with email spam.

I have next to no knowledge of roundcube, but aren't there plugins that give it spam filtering capabilities that could be "simply" turned on?

@WildEnte As i know, you should move the mails you rexcognieze as spam to Spam folder and, i hope, the spam filter of mail server will learn from that folder next day.

Thats the way my mail server and some others does it. But i may ask the server admins internally how the spam will be learned on Vivaldi mail server. Stay tuned and ask me later in case i forgot to answer.

[WildEnte]

@DoctorG so... are you saying Vivaldi.net has a working spam filter and I never noticed because I hardly ever get any spam (thank goodness) on vivaldi.net? Maybe I just assumed that there is no spam fiter running because poor @janrif is constantly trying to put together some self made spam filter?

If so I apologize for wasting everyone's time.

I do not really know much about Vivaldi mail server internas, thus why i asked internally.

[DoctorG]

@WildEnte A learning filter was never running and can not be added. Does not scale for half a million users, a server admin said, and as i understood 'You can only reduce your spam by filters and managesieve in Vivaldi Webmail."

And scalable means: many more databases, more servers, much more costs.
Not affordable at the moment, i guess.
Let us wait until Vivaldi is as large as other companies and can invest more money.

@DoctorG I'm sorry.....what is managesieve? filtering? If so, why in webmail but not in mail?

@janrif from the webmail interface (https://webmail.vivaldi.net) you can set up server-side filter rules. These rules will apply to mails before they reach your mail client. You can get to them in Settings > Filters

Managing server-sided filters in webmail.

If so, why in webmail but not in mail?

Because that is a webmail software feature.

[WildEnte]

OK understandable. I guess that M3 has a learning spam filter on the list of future features but I doubt it will come soon (gut feeling, no inside knowledge). Maybe there is an elegant solution like a third party app or a spam filter proxy one could use that the Vivaldi team can recommend as a workaround...

I for one would consider the Vivaldi ecosystem of webmail service and email client incomplete without a working spam filter.

@thomasp Tks. From this I assume the 2 email systems are completely separate; i.e. if I create a filter in webmail, I will still get the "filtered" email in Viivaldi Mail..... is that correct?

This leaves me wondering if I should switch to webmail until Vivaldi Mail filtering works better......

[thomasp]

As I said,

These rules will apply to mails before they reach your mail client.

Vivaldi Mail is such a mail client. Therefore if your server-side filter deletes the mail or moves it to another IMAP folder, this will directly affect whether or not the Vivaldi Mail client sees the mail, and where it sees it.

You can also choose to do all filtering in your mail client, if you prefer, but the suggestion about using server-side filtering was specifically to allow you to address certain patterns of spam and not have to set up the same rule in every mail client you use.

[janrif]

@thomasp Thank you. I think I understand. Can you tell me if webmail filter can filter on criteria based in raw that is not to/from/subject. I ask bc I get a lot of annoying html only spam & I'm trying to filter it out & the only common criteria is found in raw. TIA

[thomasp]

@janrif It can filter on pretty much anything:
(the ... item even allows you to filter on any arbitrary mail header).

I would suggest you check out the filter options for yourself.

@thomasp Yup. That's exactly what I am going to do. Thanks

just to link threads together, this discussion in another thread gives pointers as to how to configure Vivaldi Webmail filter to use the X-Spam filter score. https://forum.vivaldi.net/topic/77941/spam-mail/4?_=1660074281952

@WildEnte m3 should have a spam filter soon or after. It's essential to be a learning one either in my opinion.

[edwardp]

I have received two spam e-mails since last Thursday, both from the same e-mail address sent through an SMTP server showing the same domain as the sending e-mail. I marked both messages in Vivaldi Mail as Spam and it moved both to the Spam folder.

Just now, I logged into the web interface. When one was highlighted, there was now an option to mark it as Junk, which I did, that moved it from Spam into Junk and did the same for the other message.

Does moving a obvious spam message from the Inbox to Junk using Vivaldi Mail, instead of Spam, have the same effect as marking the message as Junk on the webmail side?

Thanks in advance.

[WildEnte]

@edwardp IMAP folders can have pretty much any name and it doesn't matter. Not sure what "spam" would be in Suaheli. Vivaldi only knows it's a spam or junk folder if said folder is marked as such on the server (per RFC standard). When setting up an IMAP account (and I believe also when connecting) Vivaldi is given the list of all folders, and which are the special folders (sent, received, trash, spam, ...). When you hit the 'mark as spam' button, Vivaldi will then move the email to the appropriate folder, regardless of how it is named.

In the version 6.0 RC 1 snapshot, there is a bugfix that is semi related but I don't think the source of your confusion [Mail] Messages with Junk flag but not in actual Spam folder are not shown in All Messages / Junk (VB-94145)

[edwardp]

@WildEnte When I moved the first of the two into Junk, a message box appeared that the message was successfully moved.

I thought perhaps that may have begun (or added to) some sort of learning for the server (e.g. a spam filter), so anything new with the same characteristics would automatically go into Junk upon receipt.

If it does, then does using Vivaldi Mail to move something to Junk, also add to the spam filtering?

@edwardp I don't believe Vivaldi "learns" but it does if you create a filter in Settings. HTH
