After activating the plugin in mail, it restarts and shows:

Mail has disabled the following plug-ins:
OpenHaystackMail.mailbundle
Contact the makers of these plug-ins for versions that are compatible with Mail 14.0.

I cannot confirm.
Maybe because:

sudo spctl --master-disable

As suggested by @sem1845
Disable Gatekeeper, then activate the Mail plug-in and enable gatekeeper again afterwards

[froodproton]

I don't get the point - the gatekeeper was disabled before this issue was posted.
This issue was raised BECAUSE the message occurs ALTHOUGH gatekeeper is disabled.

Doesn't the status show that it is disabled?
sudo spctl --status

Which macOS version are you using? It could be that a new Beta would require an update to the Plug-In

[schmittner]

Also I think that running spctl shouldn't throw these warnings...

[schmittner]

@froodproton were you able to get it running?

[domse]

I think the Mailplugin isn't compatible to current Mail 14 version as per openhaystack/OpenHaystack/OpenHaystackMail/Info.plist Therefore the plugin doesn't show up without another compatible Addon. I was also only able to install when adding mailbutler.

[Sn0wfreezeDev]

I checked that several times, because when the plug-in is not compatible you get an error message by Mail saying that it is not compatible with Mail 14.

What I think could be the issue is that we store the plug-in in the user's directory at ~/Library/Mail/Bundles. Most other plug-ins store it in the system level at /Library/Mail/Bundles. Mail does not seem to query the user folder for some users if they do not have other plug-ins installed

[froodproton]

I am running regular Mac OS 11.2.3
The Mac is company managed with Jamf, but I don't see any restrictions regarding gatekeeper.
/Library/Mail does not exist on this Mac.

Mailbutler is installed now and the MailButler Plugin is active, it was possible to activate it just like it is required for haystack.
But the problem with haystack plugin still persists.....

I face this issue as well on M1 running BigSur 11.3.
