Send soap via python or bash script from localhost?

Question

bash

There is Postfix and there is a script for Python or Bash. On the same server. How to send soap from localhost to some external destination? What interests me is that since the script is already on the localhost, depending on the settings, of course, it will not need to authenticate as if it were on a different server.

Answer 1

echo bla-bla-bla | mail -s subject [email protected]

everything else depends on the settings of the mail server.
