I have an issue whereby SpamSieve 2.8.8 with Apple Mail Lion using an iCloud mail account is occasionally marking trained good or Address Book related messages as spam. Looking at the log, it appears that SpamSieve is occasionally having trouble reading the From and Subject info of incoming messages. SpamSieve does not seem to have any trouble reading the Subject and From when I subsequently “Apply Rules” manually to these messages as SS then marks them as good. I’ve included the log info below for two mis-marked messages in a row this morning as well as the subsequent Apply Rules entry for the message where the sender is in my address book (I obscured the prefix of the sender’s address).
Is this to be expected, a problem with the SS Apple Mail plugin passing mail to SS or is there some other issue I should be chasing? The message headers don’t seem to be corrupted and as noted SS has no problem reading and interpreting them when the SS Rule is applied manually. Note also that this generally occurs when I first wake my laptop and Mail first downloads from iCloud all the mail received overnight. I don’t recall having seen it happen during the day when messages might be pushed to my laptop singly.
