It appears that Gmail has joined the ranks of Yahoo, Hotmail, AOL, and others with respect to their DMARC policy: https://sendgrid.com/blog/gmail-dmarc-update-2016/.
The key is that when certain email hosts follow DMARC policy, any time a message is claimed to have been sent from that identical host’s email server (i.e., a message posted by a subscriber with a Gmail email address, being read by a recipient with a Gmail email address) but which does not originate *from* the host’s servers (eList messages are distributed from Cornell’s servers), that email host (recipients with a Gmail account) will reject the message and mark it as spam or junk mail. Because all messages sent to NYSbirds-L are sent *from* the sender’s email address and then ultimately distributed *from* Cornell’s eList servers, they no longer follow DMARC guidelines and may be filtered undesirably by the recipient’s host server, depending upon your host (i.e., Yahoo to Yahoo, Hotmail to Hotmail, AOL to AOL, Gmail to Gmail, etc.). This is a primary issue with hosts following DMARC policy and is ultimately because of free email accounts being hacked or used to distribute junk mail and malware. Please take care to check your spam folder or turn off spam filtering altogether, should you find lots of NYSbirds-L eList messages going into your junk/spam folder. You can also check some of the archive sites to make sure your aren’t missing anything.
