Where can I find info on email errors #550

[Guest]

If anyone out there can point me in the right direction for an answer, I
would appreciate it.

When sending an email with an attachment, I get the message: "Your message
did not reach some or all of the intended recipents...the following
recipient(s) could not be reached...550 <[email protected]>...relaying denied.

I do know that the recipient was waiting for the email and I had just
verified the email address with them and I can't understand this.

Thanks for any help.

You need to authenticate to your outgoing server, which can be done on the
"Outgoing Server" tab of your account dialog.
