My emails are not received by comcast.net addresses.

Hi Comcast,

 

I own a business and my customers with comcast.net addresses aren't receiving the emails that I send to them.  To get around this, I use a personal gmail address but this isn't a long term solution.

 

I tested with a family member who has a comcast.net address and he didn't receive the messages either.

 

Can you help me out?

 

Thanks.

I am not.  The email address I'm sending from is tied to my website hosting.  Thanks.

The email domain we're sending from is 6gaslogs.com.  I did a blacklist test at MxToolbox and we're not showing up on anything there.

@ComcastCSAEmail Thanks for the information.  I'll forward this to my hosting provider and see what they say.
