If embedded blanks are converted to underscores on entry
into the RFC822 Internet and converted back to embedded
blanks on return into the X.400 world, what is done with
addressees in the X.400 environment which contain
underscores? We ran into the problem recently when we
found some addresses in the MCI Mail system which require
underscores. We had been converting embedded blanks into
underscores (since MCI Mail formal names have embedded
blanks). We automatically converted underscore to blank
on entry into MCI Mail from the RFC822 domain. This broke
when we realized we had to retain some underscored addresses
because that is how they were supposed to look in the
MCI Mail environment.

We found that attempting to use "\" as the quote character
did not work uniformly in the Internet (some mailers clean
up the address strings by removing the "\" characters).

Has the need for preserving underscored addresses while
in the X.400 environment arisen? If so, what has been the
preferred solution?

thanks,
