Comcast Blocking Some Yahoo Emails?

I received an email this morning from a relative asking for help in receiving email thru their Comcast account which is being sent via a Yahoo account. It seems that Comcast is filtering out some Yahoo emails because of spaming. In their response Comcast states:
“Thank you for contacting Comcast. My name is Patricia, and I appreciate
you taking the time to contact us.
I understand you are unable to receive messages from a Yahoo.com e-mail address. Comcast has recently made changes to our filters and is now
blocking e-mail messages sent from domains that do not have their Reverse Domain Name System set up correctly.
In keeping with industry standards and best practices, any e-mail sent from an IP address that resolves to a hostname determined to be in Dynamic IP space will be r ejected. When that happens, the following error message will be returned: “Comcast does not support the direct connection to its mail servers from residential IPs. Your mail should be sent to Comcast.net users through your ISP.” You will need to contact your ISP with this information so the server your e-mail is being sent from can be configured correctly.
You can find out more information about Reverse Domain Name Systems, as well as information for your ISP or Network administrator by following

Please respond to this e-mail if you have any further questions. “
Interesting. I seriously doubt contacting Yahoo is going to elicit a response nor is Yahoo going to change their server settings for one email client. Especially since these type of accounts are free and only affect Comcast so far.
My advice was to switch to a Gmail account instead.
But I guess my questions is does anyone else have this problem? If so, was there a work around for it?
Comments welcome.

Ron:
The keywords are ‘determined to be in Dynamic IP space’. I seriously doubt that Yahoo email servers use a dynamic IP address. The problem is probably not with Yahoo. Most likely the person is using an ISP service to send the email through. The block of addresses for that ISP is probably on someone’s dynamic IP range list.
Had the same problem with a client. The email sent from the client’s exchange server would be rejected for some email addresses. Turns out the ISP service for this client had all its IP address block marked as dynamic by some (very stupid IMHO) service that some inexperienced email administers used to block SPAM.
Was a big hassle to get the ISP service to step up to the task of contacting the dynamic IP detection service to delist the fixed IP addresses.

Hello zenium,
Thanks for dropping by and explaining the problem. I’ll check and see if that is the case, but these family members are inexperienced and live in another state. Whether I can explain this to them in a way they understand might be the hard part.
Thanks again. Ron

I’m having similar issues getting emails sent to my yahoo account, and it has me crazy since I’m in the middle of a job search and sometimes get emails and sometimes don’t. For example:
I get some emails from my sister and sometimes not
I get some emails from an HR rep and sometimes not
Today I did not recieve an email send from a recruiter
….and the beat goes on.
Problem is is that I’ve had this account for so long and decided to open yet another yahoo account (likely not a good idea) and the same thing is happenining on that account. Looks like I need to create yet another account via gmail.
Some facts - comcast is my ISP and I do not have any blocked settings for these people.
I sent a ’support’ email to yahoo and they sent me the usual level 1 support stuff. Today, I’ve just replied back to say “still not working”
We’ll see

Comcast is my provider, and starting a couple months ago they began rejecting some e-mails sent from certain e-mail addresses. One address they didn’t like was alaska.com and one was villagustava.de (Germany). Both are web-based e-mail addresses. The instructions Comcast gives to get the blocks removed are similar to what Zenium posted in March 08. My German contact says almost all her e-mail is getting bounced back to her, including gmail, although she can receive all e-mails. What is going on? I have gotten email regularly from both these accounts for years, and this blocking has just started.
