After updating to El Capitan from Yosemite, email that SpamSieve properly identifies as spam and moves to the local Spam folder on my Mac is now being delivered to POP clients on other computers. Previously, before updating from Yosemite any emails that were moved to the local Spam folder by SpamSieve were of course not delivered to any other email clients.
I made sure to update to the latest version of SS before upgrading to El Capitan. I rechecked the mail rule. It is correct. SS commands do appear in Apple Mail. And, like I said the spam messages are being moved to the Spam folder On My Mac as before.
I have 1&1 hosted email. Nothing has changed on their end.
Any help would be greatly appreciated. Thank you!
