We were on the brink of losing all subscribers with Yahoo addresses who are subscribed to Lactnet due to issues with Yahoo as described in the email below. Lsoft, the company who graciously hosts our list for free, has made some adjustments to address this problem with the Yahoo addresses. Please note that the issues lie with Yahoo, not Lsoft. Please read the email below carefully, especially the part about mail being potentially rerouted into your spam or junk folder. If you get deleted from Lactnet, no worries! You do not need to email us asking to be put back on the list. You can just resubscribe at any time using the command "subscribe Lactnet firstname lastname" and sending it to [log in to unmask] Kathy, on behalf of all the listmothers. -----Original Message----- From: Ben Parker Sent: Monday, April 14, 2014 4:46 PM Subject: Re: What to do about your Yahoo.com subscribers? First, let's be clear on what is happening. A subscriber/list member from *@besteffort.com address (or other private domain, i.e. not one of the big webmail domains) posts a message to your list. It goes to all subscribers. No problem for anyone. A subscriber/list member with a From: *@yahoo.com posts a message (or a reply to the above message) to your list. This will go to a few subscribers, but will NOT go to subscribers/list members at yahoo.com, hotmail.com, live.com, msn.com, outlook.com, Comcast.net, Gmail.com and several other domains. Messages to subscribers at these domains will not only not be delivered but will be bounced/rejected as if the recipients at those domains do not exist. Thus, after a few such messages with a From: *@yahoo.com, your subscribers at all of those problematic domains are at risk to be auto-deleted from your list(s). This may amount to more than half of your total subscribers! Obviously this is a very bad situation, but it is a situation made by Yahoo.com in disregard of the convenience to their users. L-Soft has installed a new build of LISTSERV on COMMUNITY.LSOFT.COM to address this problem. List messages to your lists with From: *@yahoo.com addresses will be re-written like this: Original From: Ben Parker <[log in to unmask]> Re-written From: Ben Parker <[log in to unmask]> This will prevent the DMARC rejections and related bounces from all of the problematic domains. This covers all of the related yahoo.* domains such as yahoo.ca, yahoo.fr, yahoo.co.uk, etc as well as a few other non-yahoo domains. ------------------------------------------------------------ Please alert L-Soft of any problems you encounter with this! ------------------------------------------------------------ Side effects of this change you need to inform your subscribers about: 1. Because the From: address has changed, list mail may no longer route into subscriber's expected list mail folder. Mail may instead go into a 'spam' or 'junk' folder. Users will need to deal with this in whatever way is necessary for their own mail client. List Owners should tell their subscribers about this so they know where to look for 'lost' mail. Users need to be proactive about this because if list mail stays in a 'spam' or 'junk' folder, it will lower the deliverability 'score' of all list mail for all lists from your server. 2. 'Reply to sender' won't work, because the From: address has been changed. If users want to reply privately to the sender, they will need to manually edit the To: address. 'Reply to List' will work as usual. 'Reply to All' will work but only halfway. Again the 'Reply to List' will work but the 'Reply to sender' will need to be manually changed as noted above. If you have adjusted the Auto-Delete settings for your list, you may want to wait for a couple of days to re-adjust them. If you have set your *@yahoo.com subscribers to NOPOST or to REVIEW, you can now reset them and allow them to POST messages to your list. *********************************************** Archives: http://community.lsoft.com/archives/LACTNET.html To reach list owners: [log in to unmask] Mail all list management commands to: [log in to unmask] COMMANDS: 1.
