This is the qmail-send program at sourceware.org. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. : User and password not set, continuing without authentication. 173.194.202.27 failed after I sent the message. Remote host said: 550-5.7.1 Unauthenticated email from yahoo.com is not accepted due to domain's 550-5.7.1 DMARC policy. Please contact the administrator of yahoo.com domain if 550-5.7.1 this was a legitimate mail.
