So I was reading the last section of this page and it talks about knowing if there's a problem sending an email.
As a test, I use:
- my personal Gmail acct (I got the email on this one)
- a fake email using the company domain (e.g. myfakeemailhere123456789@companyB.com). I know it's going to be fake since our company uses some standards for their email address.
and both resulted in returning a blank array.
Any ideas what I could be doing wrong?
edit: I'm using postfix that's locally installed in the server.
