Cannot send emails from business domain to @comcast.net email accounts
Hello, I am experiecing difficulties sending emails from my business mail server. The end-users from lennar.com are not having any success relaying emails to accounts using comcast.net. Can you advise if there any suppression settings set on the lennar.com domain? I have tried sending test emails from my business email to [edited for forums violation].net (my comcast acct) but it's not successful. I also attemtpted to delist our two static ip address for outbound mail flow, but I received the automated notification that neither ip address is on the block removal list. I also performed a test message trace from Lennar's Proofpoint console and the communication was successful. I can provide the logs upon request. Thank you.
