Random e-mails bouncing

I had this problem about six months ago where e-mails to various customers and friends were randomly bouncing back.  I talked to various tech people finally getting a more senior tech analysis who knew of the problem and told me that some of the companies that safeguarded against spam had targeted Comcast and that Comcast was working on the solution to resolve the problem.  I was happy for the solution which your tech staff figured out, and my e-mail has been working flawlessly until about 10 days ago when I started to get the problem again.  The random bounced e-mails are coming back from both clients and friends where I know that they have not blocked nor targeted my e-mail address as spam.  This is the error I, along with others within our company, am seeing:  Reporting-MTA: dns; []
Received-From-MTA: dns; LynetteVAIO []

Re: Random e-mails bouncing

Hello whitei,


Welcome to the forum.

Community would like to assist but could you clarify few items for us?


1. Your domain name

2. Any changes made on your network, if any

3. Do you use an email client or webmail when sending your emails?

4. Have you try to send emails via webmail?



Thank you
