As I tried to explain in another mail, I'm not really clear on this. The sender should not send an address that the receiver doesn't know how to read.
The problem is that there may be multiple recipients and the sender may not know which recipients can read which languages, or even if this is known, the sender may not know alternative addresses for some of the recipients. Consider a reply to a message that was originally sent to a list of recipients, some of whom the sender knows and some of whom the sender doesn't know. Either the original message or the reply could be in multiple languages (say with multipart/alternative)
Do you have information on how often multiple languages (with multipart/ alternative or plaintext, but nevertheless parallel texts) are used? My guess is that they are very rare. Preparing messages in multiple languages is everything but cheap.
