I just updated to v3.1 of Spam Sleeve and cannot figure out how to set it up with Canary Mail.
Sorry, but Canary Mail is not one of the supported mail clients. However, it is possible to use Apple Mail to filter the messages with SpamSieve while reading your mail and training SpamSieve from Canary Mail.
Oh… that stinks. Will you be adding support for Canary Mail? I gladly beta that. How would I use Airmail to do this?
Canary Mail is not sufficiently extensible for us to connect it with SpamSieve. We have offered to help the developers add support for SpamSieve, and they have expressed interest. Sending them feedback (click the blue-and-white icon at the bottom-right) will help them prioritize this feature.
Currently, remote training is only available with Apple Mail, MailMate, and old versions of Outlook.
