I keep thinking that we may need to factor in the possibility that the developer who wrote the message may not have English as their first language. That said, yes, it is possible that the receiving end has implemented per user (or per alias) rate limiting for *receiving* messages. Which would be, let's say not the first thing I would have thought to do myself, but may conceivably be the case. The reason I focused on the source address and NATing as a possible explanation was that they managed to get their messages delivered from a different location. It would be interesting to hear from whoever is in charge of the receiving end here about what it is that they have implemented. -- Peter N. M.
