You might consider storing the unecoded address. If you are using an MTA that
doesn't provide a way to input unencoded addresses (e.g. sendmail), you can
encode the address before passing it to the MTA or adding it into a header
if you need to do that. It isn't even that hard to tack on the person's
name (from somewhere else in your database) or other comment on when putting
the encoded address into a message header.

When collecting input you might ask for confirmation when seeing unusual
addresses. This should cut down on the number of bogus ones that get into
the sysem.
