This is the return e-mail from my linux box. Let me explain what i am doing, i am using sql to send e-mails out to our mail server, well now they are bouncing. this linux box is local and the mail server is with a manged host. I don't understand this error and how would i find out what is wrong so i fix it? I am only sending e-mail i don't need to receive.
I think your mail server is doing recipient / sender verification before accepting the email for delivery. This is great for reducing SPAM accepted by servers, but not so great for the firstname.lastname@example.org
omain kind of email notifications we like to receive.
I don't (yet) know how to fix this - hoping someone out there can lend some advice, as I'm seeking the same.
