We are using % as a "masked @ sign" for this application.  An address
could, for example, be expressed as:

zben%umd5%umd2@umda

When umda gets it, it strips its name and changes the rightmost % to @:

zben%umd5@umd2

Similarly, umd2 changes it to:

zben@umd5

and I eventually get the message.

Within the context of RFC822, a suggestion is to use the doublequoted
string for this.  Note that there is a thing in the sendmail configuration
file that says "this is a final delivery".  If set, then doublequotes are
removed from the address before passing it to the server.  Thus one could
in some circumstances use something like:

"zben@umd5"@umd2

although we do not support this at the present time.  There seem to be
both pro and con arguments on this, and I am going to let it ferment for
awhile before I do anything with it...
