I beleive that the e-mail problems which have plagued us
over the past week have been resolved.  Both addresses,
ibmstandards.cary.ibm.com and networking.cary.ibm.com
appear to working in a reasonable fashion.  So let the
e-mail flow...

PS:  For the die-hards, who would like to know what
was causing the problems:

  1. One partition was too small for its usage.
     (The partition where incoming mail was stored.)
  2. AIX V3.2 sendmail doesn't seem to like uppercase
     aliases in the alias file.
     (For those who saw something like - unknown user: aiw-G1 or
     ciw-G1)
  3. The Biggie - a DNS lookup was being done for every address
     in a mailing list, before incoming mail was accepted for the
     mailing list.  This was too bad, except for things like the
     approx 300 addresses on aiw-general.
     (This just took too long.  Most systems (all?) attempting to
     pass mail to us were timing out because of the length of time
     to do all the lookups - one at a time.)
