I am not receiving email notifications from your email address firstname.lastname@example.org. My email provider Comcast says the address is whitelisted.

We have been having ongoing issues with @comcast.net email addresses rejecting emails. The issue according to comcast is the following:
554 - [PTR lookup failure] Comcast requires all sending mail server IP addresses have a valid PTR record set up. This error results when the lookup failed. NXDOMAIN response. One of the authoritative servers for the relevant section of the in-addr.arpa DNS tree is saying that there is no PTR record for the given IP address.
There are a few other users who have reported the same. Usually though, the email address shows up on our bounce list due to rejecting emails. Yours was not. Check your spam/junkmail folder to ensure the emails are not being filtered there. If they are not and you require using a comcast email address, you may want to try sending the emails from your own address via SMTP:
