Hi Doug,
Welcome and thanks for posting!
Thanks to your code and Mohan we have html email running on SloanSpace for a month or two and we haven't seen any problems yet. We have medium volume, not sure how many emails but we have 9000 registered users, just under a 1000 users log on each day. We use html for both notifications (forums and survey) and bulk-mail. Half the users complain about getting too much mail, the other half keep asking for more ways to send spam :) but the aolserver and tcllib hasn't given us any trouble.
