That appears to be an rfc 2822 address. RFC 2821 addresses are more limited
in that they can't have comments but still escape special characters.

What you want to store depends on what you are going to do with the address.
If you don't need the comments, storing it as a local part and a domain
is probably best.

That would depend on whether or not sending to those addresses would make
sense in your case.

Email addresses are in ascii and hence bytes should only contain characters
with the codes 0 through 127.
