Postbox 7 BETA Supports add-ons/Labs. Is there a chance to get SpamSieve in there?

It looks like Postbox is opening their support for third party add-ons again.


Similar to add-ons, our Labs feature will allow for experimental 3rd-party code to be used within Postbox.

The first Labs project will be OpenPGP support provided by a specially designed version of Enigmail for Postbox and can be enabled under the Tools menu (remember to add the appropriate buttons to the Compose window toolbar).

Unlike add-ons which can be arbitrarily installed, only a select number of Labs projects will be available for Postbox. Given that Labs projects contain 3rd-party experimental code, they are not officially supported by Postbox, Inc.

If there’s a 3rd-party solution you would like to see in Postbox, contact the 3rd-party developer directly. Please do not contact Postbox asking us to support code we do not develop, thanks!

SpamSieve has been invited to join the Labs program, and we’re working with them. However, it’s not yet clear whether it will be possible to make an add-on for Postbox 7, as a lot has changed under the hood.

Just adding another voice for this. I’m staying at PB 5.x until SpamSieve and PB 7 play nice, so I’d love to see this happen.

If there’s anything a random but happy user of both products could do to encourage or support this, please let us know.

Throwing my virtual hat/cheer/hopes and prayers into this one-- I’m still using PB5 for the same reason. Even without direct SpamSieve support, I doubt their built-in spam filtering would allow importing the massive corpus I’ve built up over the years using SpamSieve. I’m not about to drop all of that now.

The same here - I stay on Postbox 5 until SpamSieve is fully supported/integrated
without that Apple Mail solution. After using SpamSive for over 14 years I don’t want
another solution - it’s perfect for me :slight_smile:

Best wishes


Any updates on this?

Not yet. The current priorities are Catalina and SpamSieve 3. Then I plan to take another crack at the Postbox plug-in and/or try to find another way to integrate with it.

SpamSieve… 3?

This is intriguing to me, and I wish to subscribe to your newsletter…

Postbox 7: I am 10 days into the trial…
FWIW, Postbox 7 is a VERY nice mail client. I am still using 5 as well, but 7 seems to be quite good. I like the way most everything works, except for a couple things that seem obvious they should be toggle-able in Prefs, but are not. So far, the SPAM filtering is pretty good. It was at about 90% after 2 days. After those 2 days, I saw only 1 false positive; since then, none. Today is the 10th day playing with version 7, I am getting about 1-3 SPAMs daily in my Inbox that Postbox missed. Overall, I think it’s a very nice app. If Michael can get SpamSieve working with Postbox, it would be the ultimate mail client for me.

Anyway, until that happens (fingers crossed,) I recommend you guys try it out. Most of the common keyboard shortcuts are the same as v5.

(And no, I am in no way affiliated with the Postbox people. I just thinks it’s a pretty great app and wanted to share that here.)
