Incompatible Plug-ins Disabled - what is this for?

macos Ventura 13.4

Hey and good day,

When clicking on an email address on a webpage, it get this error message and I dont know what to make out of it:

Incompatible Plug-ins Disabled
Mail has disabled the following plug-ins:
Contact the makers of these plug-ins for versions that are compatible with Mail

Should I- as mentioned before - “download a fresh copy of SpamSieve and choose “Install Apple Mail Plug-In” from the SpamSieve menu.”

with best regards,

Which version of SpamSieve do you have? If you have at least SpamSieve 2.9.52, you probably don’t need to redownload it. Instead, follow the Enabling and Updating the Apple Mail Plug-In instructions.
