Hiya, My name is Mike and I've been repairing and upgrading computers for over 10 years, I will help you to the best of my ability.
When does this error occur?
looks like an attempted mail send and it bounced back
but the more info you can provide me the better :-)
Does it do it to anyone else or that person only?
That person only. I have had others on Comcast send e-mails to him, they get to him
This has been goin on for almost 2 qweeks
Are you typing it in manually or using it from your address book?
Both and reply to his e-mail to me.
Can you contact him and see if he has accidentally blocked your mail from coming in which will cause the bounce back
I have and he has NOT
Have you double checked his email address for tiny mistakes?
I have sent messages to him from 3 different emails that I have. Every one returns. They DO NOT return if I send it through the WEB
Do you use comcast direct ot through outlook etc
Ok so if you go to comcast online through web it works fine?
The problem is, ive experienced this problem with all recipients but not an individual email returning every time
You know I have a number of E-mails from Just answere saying that you have answered my question. Where is that answer. You are not helping me so far.
Im going to open this up as I am unsure how to proceed with this senario
So, how long d I have to wait?
What you say is very informative, but if I ever had McAfee on ANY computer I would shoot myself.
So now what?

FYI I got the guy I have been trying to e-mail to make a Gmail acct. We got his Outlook to read it and guess what, My e-mail to that adress from my outlook got to his outlook.
I will get with Comcast and read what you have said, tomorrow. If it clears it up I will accept your answere then. IN the meantime you need to get a chat window that is two way. The other guy had that, you do not. I am sitting here thinking your reply would show up in the existing chat. Have a good night,
Mike, I am not done with this. I am on the road at times and it does not make sense for me to communicate with you. I am home now and you are right, Comcast told me they do not blacklist. I have talked with them almost every other day. I have one person, he gave me his extension, that finally understood what was going on and said he had a friend that was a guru. I was not able to talk with him today, maybe tomorrow.
What I have proven is that if I turn off the wifi on the iphone and use the 3G, the e-mails get through. I have gone nextdoor to neighbor and used his(Comcast) wifi on my iPhone, the mail goes through. We live on a culdesac and share the main comcast line, it is the end of the line.
The only thing that I can think of is that the Motorola Surfboard is bad, but I can not see that. I am only talking 2 email addresses. One gets bounced back and the other never gets there, but I do not know it.
I looked at the links you had, I am afraid that I was not able to fully understand them.
ONE of the computers is "dell"
Remember I am only getting ONE returned e-mail and I am getting one e-mail that does not get to the sender, but not returned
That's not something I remember you mentioning.
In your chat transcript, you had mentioned emails to 3 people that were getting returned.
For the one that the sender is not receiving, but you are not getting a bounce back for, it will be difficult to verify what is hapenning to the email because whatever that is happens after the receiving server has accepted it. If you don't get a return saying that it wasn't deliverable, then as far as you are concerned on your side, the message was successfully sent and accepted. It's very likely that in this case the receiver has a rule or block of which they are not aware. So we have to concentrate on the one that you are getting the response about.
What happens if you send an email to yourself at comcast from Outlook?
Then the only thing that could possibly be responsible us the individual IP address you are being assigned at your house.
You can do a couple of things to test this. The first is sure to give you fewer headaches if it works.
Unplug your cable modem and your router for at least an hour... overnight if you can. Reconnect the cable modem and then your router. This should get a new DHCP IP address from Comcast.
Call comcast and tell them you need to reset your IP address because it's blacklisted. The main problem with this will be getting someone that understands what you are asking for.
Actually, that's how you do it.
Just open your browser and go to
That will give you your external IP address.
