att mailx under osx4.4

[era at NIWOT.UCAR.EDU]

Are there any att universe experts out there who can give me
advice on a (hopefully) small problem with att "mailx"?

We recently upgraded our pyramid from 3.1 to 4.4.  Users who run
in the att universe found that "mailx" stopped working.  Since
most of our users run in ucb and most of our mail is ucb-based,
I took the advice of the mailx man page and did the following:

o In /usr/.attlib/mailx/mailx.rc, I put in the line
  "set sendmail=/usr/.ucblib/sendmail" so mailx would use sendmail.
o In /usr/.attlib, I created a symbolic link
  sendmail.cf -> /usr/.ucblib/sendmail.cf.

After making these changes, attempts to mail to a local user
result in the message going into a black hole; nothing ever appears
in /usr/spool/mail, mailx prints no error messages, and nothing is
returned to the mailing user or to postmaster/root.  Executing
"mailx -d" doesn't result in any debugging output which appears to
be of interest.

Thanks in advance for your advice -
