E-mail headers. Bounce back e-mail. SMTP relay. Unable to unable to relay 5.7.1.

Hi there

- Can someone please advise me on what are the information that can be most useful to analyse bounce back messages is it bounce back messages or the e-mail headers?

- Can someone please give me one good simple explanation on SMTP relay. (A good link will do)

- Many times I have seen this message: unable to relay 5.7.1 when users tried to send from applications. Can some one explain that to me simply and briefly.

Thanks

Thank you very much

But still question no. 1 is not very clear

What is the difference between e-mail headers and bounce back messages, which is more descriptive of the problem?

Thanks
