Comcast blocking messages
April 27, 2009, 12:26:53 pm
It has come to our attention that within the last 3 weeks Comcast message sent to comcast are not being received.

We did a quick check and using our own Comcast accounts and discovered that the Comcast email users must change their filtering options, to "Keep a local copy in my Screened Mail folder in Webmail."  Even with this change, messages still end up in the spam folder - but at least they are being delivered.  Adding the sending email to the address book does not resolve this issue any further.

Comcast.net email addresses have been a issue in the past, which is why we switched to using your service.  Please advise.

(Shane I have not heard back from you regarding this issue)

hi,

we have done a test mailing with our own test comcast account and all worked without any special settings in the comcast account.

the message has been delivered with no problems into the inbox.
subscribes, unsibscribes and replies all worked with no problems as well.

we have also double checked all blacklists as well as comcast specific blacklists and our ip is clean.

this might be some issue specific to your comcast account/s, your newsletter domain or content that you are sending.

i will contact you with details on our test comcast account so you can try sending your test mailing to that address and we can debug it from there.

thanks,

Leyla

I've come to a resolution on this that I thought I should share. 

Long story short - our users were marking messages from us as "spam", so comcast's email system automatically blocked messages that included similar headers.  Our server was not being blocked via ip address, so checking the comcast blacklist did not help resolve the issue.

The moderators on the comcast forums were very quick to help me resolve this issue (within about 4 hours after I had originally posted).  I posted the header from the emails that we were sending out and comcast updated their white-list.

Comcast Forums: http://forums.comcast.net

and additional resource that may help you resolve issues further in the future can be found here:  http://feedback.comcast.net

Now I need to educate our users how not to mark messages as spam.
