Cannot Send, Error

[Guest]

I can receive emails, but cannot send out. I get the error "Relaying denied,
proper authentication required". The server is right because it works when
using webmail to send, but not through outlook. Have tried numerous setting
changes, such as checking box for outgoing mail authentication. The server
is of the type "name.info" Please help me out. It's Outlook on Office XP
small business.

Webmail & SMTP are two entirely different things so one may work while the
other won't. Usually relaying means that you're on a different network from
the SMTP server and it's denying your mail since you're not on its net.
Typically ISPs will refuse to accept mail on their SMTP servers when it's
sent from clients not on their net.

Talked to the ISP and used their SMTP server this time to try it. That also
didn't work giving the same error. The error number is 550 5.7.1 I can't
figure this out.

Hi,
maybe this discussion could be a solution

The ISP said port 25 was not blocked. But, if it is (because they seem like
they're not very bright) how would I check if it's blocked and how would I
change that?

You can see if port 25 is available on their server by opening a command
prompt window and typing:

telnet yourmailserver 25

where "yourmailserver" is the name of the SMTP server (not the POP server)
your ISP provides. If you get a banner response (a line identifying the
SMTP server), then you know they're telling the truth. Type QUIT to end the
telnet session if you do and CTRL-C if it just sits there and doesn't time
out after a while. If you get no response, or you get a response that says
"connection refused" (or something similar), you'll have some ammunition for
your complaint. You can't fix it. They must.
