hotmail bounces ymail.com addresses
I get this error message at least once a week when email friends I have been in touch with for years, simple emails with text (no graphics, no links)!!!
In this case it was to a hotmail.com email address of a friend who I have been emailing several times a week for a decade or more!
550: 5.7.515 Access denied, sending domain YMAIL.COM doesn't meet the required authentication level. The sender's domain in the 5322.From address doesn't meet the authentication requirements defined for the sender.
