In my experience, both AOL and Yahoo email addresses have been a problem for at least 10 years, and the problem is from their end, not ours. On the other hand, why are we sending out monthly subscription reminders? Aside from the routine unsubscription of AOL and Yahoo accounts, do we have any reason to believe this is a useful exercise?
Incidentally, Mark, the link you provided is listed as "suspicious" by my security system (Norton)....is there somewhere else we could read that information?
