So here's something odd. I have not been using email alerts since my last post in this thread. Just now, I got a text message on my phone (and NOT in my actual desktop email client) saying: This is the mail system at host bbtpnj33wzwvetm-c-nk-x-00-mms-01.vtext.com. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message. The mail system <my_email_address@gmail.com>: host gmail-smtp-in.l.google.com[142.250.9.26] said: 550-5.7.26 This mail is unauthenticated, which poses a security risk to the 550-5.7.26 sender and Gmail users, and has been blocked. The sender must 550-5.7.26 authenticate with at least one of SPF or DKIM. For this message, 550-5.7.26 DKIM checks did not pass and SPF check for [mypixmessages.com] did 550-5.7.26 not pass with ip: [63.55.6.104]. The sender should visit 550-5.7.26 https://support.google.com/mail/answer/81126#authentication for 550 5.7.26 instructions on setting up authentication. m125-20020a0dca83000000b005419f431a0bsi13764563ywd.105 - gsmtp (in reply to end of DATA command)
