All out-going email rejected

[charles.kendricks]

I am trying to use Outlook with my personal email account. Whenever I
try to email anyone other than myself I get the message:
The following recipient(s) could not be reached:

'(e-mail address removed)' on 5/10/2006 10:57 AM
550 #5.1.0 Address rejected.

I thought that I had set up my email account the same way that I have
in the past, and when I run the test of the configuration during
account setup it seems to pass the test OK. Am I doing something
wrong, or should I be contacting my ISP?

Are you on the same network as the SMTP (outgoing mail) server you're trying
to use?

 

[charles.kendricks]

No I am not on the same network as the SMTP server. The server is
administered by my ISP and I am trying to send mail from work or from
wifi hotspots. I configured Outlook to point to the SMTP server of my
ISP though.

That's the issue. Most SMTP servers block access from outside networks...

No I am not on the same network as the SMTP server. The server is
administered by my ISP and I am trying to send mail from work or from
wifi hotspots. I configured Outlook to point to the SMTP server of my
ISP though.

Then log into the ISP's server using your ISP's credentials. Specify them
on the Outgoing Server tab of your account properties.

That still might not work. My mail provider doesn't offer authenticated SMTP
access, sadly
