I get the following Lookout error when using the Mailer object to send emails:
Email authentication is failed. SMTP error 535 5.7.3 Authentication Unsuccessful
It works just fine from my office location and other locations, but when I run the same program at my customer's location I get the above error.
I had the IT tech at AT&T open up port 25 on my customers internet account. Before she opened up the port, all I would get
is the error: Timeout during connection to SMTP server.
We use our company's SMTP server in the Mailer object, The SMTP requires authentication
