As distributed, MAXATOM (in src/conf.h) is set to 100. This is the
allowable number of tokens in an address. "eric@berkeley" is three
atoms.

Addresses longer than MAXATOM will get truncated. This usually
creates addresses that look like:
	one!and!another!hop!thru!bel!tel!land!before!we!reach!ihnp4!

With the address getting chopped off somewhere in the middle. Sigh.
Unfortunately, this also seems to be the way that sendmail is
distributed with other systems (Pyramid).
