Contact Form plugin email is not being received, not clear if it is being sent I am using the Pixel &amp; Tonic Contact Form plugin.  I set it up using the Mijingo tutorial.  Everything appears to be working ...

I hit submit, redirects to thank you, no message received.  Setup looks good.  Hidden input fields appear good.  Error messages working when required inputs (fromEmail and message) left blank.  Redirects to thank you.  Honeypot setup looks good.   But, no message received.  And I don't know how to confirm it is really being sent.  What might I try? Thanks

I am in dev mode
There's a good article here for troubleshooting email errors and well as email deliverability issues: https://craftcms.com/support/troubleshooting-email-errors

TL/DR: Don't use PHP's mail/sendmail methods in production and even in development, you aren't guaranteed email deliverability with those.
