Are you getting your Notification / Subscription emails?

Thanks for the input guys. Ok something is definitely up with the Forum Subscriptions. I really don't want to cause these emails to trigger Gmail's spam filter and start putting all Stew mails in the Spam box. If I can't come up with a solution I will evaluate their usefulness and take appropriate steps.

I think it may be the HTML content of the forum subscription emails that is the trigger. Text-only emails still seem to be relatively ok.

Investigations ongoing and comments / reports are still very much appreciated.
