I am using Mac Mail with the latest edition of Mac Sierra. I installed SpamSieve, created a local folder on my Mac Book called spam with my IMAP mail accounts - and enjoyed working with the trial for a day.
I then thought I ought to change to having a Drone using my IMac. I uninstalled SpamSieve on my Mac book using the procedure in the guide including removing the rule and the SpamSieve files from the library and did a restart.
The spam folders on my IMAP accounts remain. I have checked server side and the folders are not there. I looked under Account Info and the spam folder is there.
The spam folders are also on my IMAP accounts on my IMac. I have tried deleting them without success. I have enabled Junk and disenabled it, I have restarted the computers and searched for any reference to spam or SpamSieve in the account details without success and the spam folder still remain. There is no rule on the macBook or the Imac. I have click rebuild and the pesky spam folder remains.
As the folders are not server side I can only conclude that it is something in Mac Mail that is causing the problem.
Any suggestions as to how to get rid of the spam folders would be appreciated.
