I am getting an error when trying to send an email to a customer as a test during setup.

1. E-Mail Transport Method smtpauth
2. SMTP Email Account Mailbox [email protected]
3. SMTP Email Mail Host mail.laidlawgifts.com
4.SMTP Email Mail Server Port 26

Email Error: SMTP Error: The following recipients failed: (my personal email account as a test)

So... any idea what I need to fix?
I did try smtp instead of smtpauth but same error.
I confirmed the email host and port.

Help
