[net.mail] making pathalias run faster

honey@down.UUCP (code 101) (02/03/84)

what with the thousands of sites in my pathalias file, it occurred to
me that bellovin may not have anticipated the sheer volume of data, and
that his hash table might reflect his assumptions.  sure enough, NHASH
in def.h is 73.  i made it a nice round number, say 2039.  this makes
the data space utilization a little bigger (up to 1014k from 993k), but
it runs in 1/3 the time (5 minutes instead of 15).
