A month ago, I received an email from a visitor to my online business, containing a simple suggestion. Thereafter, I keep getting the same freakin email in one-minute spurts every now and then.
For example, this morning I received the same email this morning at 9:36,37,38,39, ...,47, then it stopped. It started up again at 12:27,28,29, .., up to 12:35. This sort of thing has been happening every few days. Hundreds of them. And, the contents of this email isn't spam or anything and was (originally) a genuine user suggestion. I contacted the original author and he says he doesn't know what's up.
Does anybody know what the heck could be going on?
