I’ve been trying to track down why users have stopped receiving any mail from yahoo users and after searching the logs and even going so far as to create a yahoo mail account and send mail to myself, I see no attempts by yahoo to connect to my server. It seems anything sent to my mail server simply disappears. Showing the gross incompetence of yahoo, there is no NDN generated, so the sender has no idea the mail has not been delivered.
I know this isn;t a postfix problem since postfix is not ever getting anything, but I’m hoping someone on the list has some ideas? -- When the least they could do to you was everything, then the most they could do to you suddenly held no terror. --Small Gods
