[gentoo-user] basic trouble with sendmail config

[Harry Putnam]

After setting up the files for sendmail on my first attempt at
sending a msg I get this error as reported in the smtp conversation:

   Temporary system failure

That is a new one to me, and doesn't give much to start on.

It appears not to even get past the submit agent.

(Running a little script that uses mailx in verbose mode to capture
the action .. Runs the mailx command as shown below:

  harry > tmail hputnam3@×××××.com
  sending like this:
  mailx -v -s "TEST 161204_134640 g0" hputnam3@×××××.com < /tmp/msg-161204_134640
  hputnam3@×××××.com... Connecting to [127.0.0.1] via relay...
