There has been some change to Gmail that is resulting in these "excessive bounce" messages that many folks have been getting. When the listserv server sends a message out, if it can not be delivered or gets rejected by the subscriber's email address, the message "bounces" back to the server.  The server tries again. When the message gets bounced back 5 times, then the server sends an automated message to the subscriber that their account is being disabled. If you have gotten these messages, your mail provider has chosen to implement anti-spam measures that sometimes are triggered by mailing list traffic. You don’t see the messages precisely because your mail provider returned them — they “bounced.” Comcast, iCloud, Gmail, ALL have increased the type of “reputation” checks they do, in addition to verifying that incoming messages adhere to relevant standards. It’s very hard to participate in global email at this point, as the big mail providers keep getting pickier and picker. Our list follows all relevant standards, but that doesn’t prevent us from running into this problem. All that I can do at this point is to re-enable all of the accounts that got the excessive bounce messages.  I just did this to several hundred accounts.  Hopefully we will be able to figure out what the issue is and resolve it, but I am just the moderator and do not know a lot about the technical end of things.  I get a notification in my email for each account that is being disabled, so I know when you are getting an email about this.  Usually I get a large group of notifications at a time, so I know it is time to go in and re-enable a group of accounts. I am sending this out as a posting that should go to all the subscribers, but if the message bounces back, then that subscriber will not see this explanation of why they did not get the message. Bob
