Helo command rejected: need fully-qualified hostname

Asked by rcoast in Simple Mail Transfer Protocol (SMTP), Microsoft IIS Web Server, .Net Editors & IDEs

Tags: helo, hostname, c#, smtp

I'm using C# to send emails... and I get some rejection notifications that contain the following line:

Diagnostic-Code: smtp;504 5.5.2 <drjohn>: Helo command rejected: need fully-qualified hostname

How do I fix this? Is it in my server configuration? DNS? or C# code?Start Free Trial
