- Getting Postfix to Send Mail From a Comcast Network
https://justatheory.com/2009/03/postfix-and-comcast/
Since I moved to Comcast a while back, I have not received emails from this blog server telling me that comments have been left. This is a drag because spam comments can pile up for a while before I think to go looking for them and delete them. So today I took the time to figure out how to get Postfix to send mail through the Comcast server. Kudos to Kclug mail list post by “Lucas,” which explains the issue in very simple terms. The key is to tell Postfix to relay mail through the Comcast mail server on port 587 (which is the correct port for Comcast to use for their users to send mail) and to use your Comcast.net username and password to connect. So I put this in my main.cf:
Follow #mail on RSS or use the
JSON API
curl -X GET \
-H "Content-type: application/json" \
-H "Accept: application/json" \
