No offence to the developer but this piece of software does not work!
I have two accounts, a corporate email which i don’t want spamsieved (as we use MessageLabs’ corporate service), and a mac mail, both on Mail. It took ages how to figure out how to not spamsieve the corporate account.
However now any legitimate emails on the Mac account ALL get moved to the Spam folder. Including those that i email myself from my work email as reminders to read up later, amazon receipts, itunes receipts, store purchases, my AMEX statements, etc etc. Literally all legit email. All of which i have trained as good at least 50 times but still no joy.
