All good. Then I realised that GrowlMail isn't displaying any of the message body for messages I receive, regardless of whether in the display options of the Growl preferences pane I have selected limit to 2-5 lines or not.
I'd be most grateful if anyone can help me to get it to work, as it'd be very cool indeed to have message body previews
And I've seen that Growl *can* display the message text as well as sender and subject using bubbles, as I've seen it do so via SpamSieve on a friend's machine.
That's just about the point at where I got stuck and came running to you for help.
