"Prefixing" X400 Addresses

[Rick-2CA]

X400 addresses must follow a strict format that doesn't allow the configured prefix to be applied at the beginning of the address string. To attempt to work with that requirement code will be committed that puts a prefix on the 'surname' portion (S=) of X400 addresses.

This solution obviously only works if the address has a surname configured. I'm not certain at this point if it'll be a widespread issue or not. If this is a thing please comment with your environment's scenario so we may explore changes.
