the "purist" view is that you should not rewrite the message, including headers. This is the job of the client mail agent. trying to rewrite/fix will generally cause problems, because it is hard to guess what the user wanted to write. and if there's a problem, the general principle applies: fix problems at the source. on the other hand, if you know what you're doing, it's ok to fix things. but think twice before you think it's all right. and think 7 times before fixing inbound mail.
