Using Apple Mail in Yosemite 10.10.1
SpamSieve 2.9.18
With every attempt to select the “Train as Spam” command (or keystroke), I get a spinning beachball after the mail disappears from the list. I am now getting this error in the console: SpamSieve Apple Mail Plug-In [Train as Spam] Error Moving to Spam Mailbox: Mail got an error: AppleEvent timed out.
This occurs when selecting a single email.
I can quit SpamSieve and eventually mail will recover.
This last time I found that the email I was trying to “train” in the trash folder after mail recovered, NOT in a spam folder. I’ve got the standard SpamSieve set up and have disabled Apple Mail junk filtering.
Is your inbox on an IMAP/Exchange server or a local/POP mailbox “On My Mac”? Is your Spam mailbox on a server or a local mailbox “On My Mac”?
As a workaround, you could try setting it not to move the messages that you train. To do that, choose SpamSieve - Change Settings and leave the name of the spam mailbox blank.
