Comcast Blocking Email to Comcast.net Accounts
We have identified an issue with Comcast blocking email being sent from c4.net to comcast.net accounts. At this point, we have notified Comcast of the issue and are waiting for them to address the problem.
An example of what the error message will look like if you try and send an email to a comcast.net address from a c4.net address is as follows:
Your message has been delayed and is still awaiting delivery to the following recipient(s):
(Was addressed to recipientName@comcast.net) Message delayed
If you are currently setup so that your mail forwards from a c4.net account to a comcast.net account, you could opt to temporarily remove the forwarding. In this case, you would need to setup your email clients to check both mailboxes.
Until there is a resolution provided to the issue, email sent from c4.net to comcast.net accounts will still get blocked. In the interim, one possible workaround is to use a free email account such as Hotmail or Yahoo to send out mail.
