How do i verify that sendmail is working?
A1: Using sendmail in verbose mode is a good method for verifying sendmail is working and how the mail is sent. To do this, run the following command: > /usr/lib/sendmail -v “some user address” this is a test of sendmail…. . Sendmail will then give a verbose output. See section 2.0 on “Debugging Sendmail” for further info.
