RFC 2821 says "The maximum total length of a reply line including the
reply code and the <CRLF> is 512 characters." That's pretty long so
maybe you never reach it. I think I'd still make $names a substr of
itself to make sure.
Some of the office-memo systems like Exchange and Lotus Notes can
throw away or hide SMTP error messages and replace them with generic
messages like "You do not have permission to send". It can be pretty
hard to get a good error report from their users (and it's not the end
users' fault that it's so hard).
