I think adding such checks and issuing a syntax error in the <xyz@domain'> case would be the way to go. But maybe there's a good reason why Courier doesn't do that?

Well, I don't think you'd have too much trouble sticking an apostrophe into a hostname in DNS. If you really wanted to, I think you could set up an MX record for foo'bar.example.com.

But that's a stretch. Obviously apostrophes are invalid, however I don't want to start keeping track of which characters are valid in DNS, and which ones aren't. You'll never get this right.

RFC1123 clearly defines valid hostnames and DNs. I would not check the prescribed lengths, but the allowed characters are easy to check.
