If you want to be international, you don't even try that. You let the communication say "Dear $Name" and you are done. Even if it means none of the emails say what you want it to say. And yes, even for a US system I don't think it's a good idea to ask for first/initial/last or to ask for formal/informal. Chinese users in the US will be happy to just see a "Name" field. Just ask for a name!
I'd stay away from gender/greeting too. Mr/Ms/Mrs/Dr etc. are way too culturally narrow even for the US.
interesting. If the message is in English, would such rules still apply? We are talking about formatting a message with a foreign name (origin unknown) in a known language, e.g English.
