hMailServer SENT: 550 Delivery is not allowed to this address
November 18, 2008
hMailServer is a great mail server substitution for the built in IIS SMTP server, I used it for years without a problem and best of all it practically free. The other day I configured the “WordPress-Ready Contact Form v.2.0WP” on a blog. I tested the form and it indicated the email was sent but I was not receiving the emails. So I opened up the hMailServer Administrator tool and clicked the “Status” list item on the left then the “Logging” tab and fired of the logging by clicking on the “Start” button.
I then opened my WordPress contact form and wrote a message and Submitted it, the form indicated the message was sent but the hMailServer logging results indicated otherwise (”SENT: 550 Delivery is not allowed to this address.”). After some research and tons of reading I found the solution (no need for you to go read forums!!)
Open “Settings” , “Advance”, “IP Ranges”, “My Computer” and check “External to external accounts” and click “Save”
that is all there is to it. hopefully this resolves the issue you were having.
Thank you.. That helped.
