Can Receive emails but not send

I have been using Microsoft mail with no problems for four months. I do have
a small business domain name. On Friday I changed companies hosting the
incoming mail server. Now I receive mail...but get all sorts of errors when
trying to send. Mainly, that the email cannot be relayed. The server host
says it can't be them because they only send. My IP (Qwest) says it is not
them...I'm caught in the middle with no solution on the horizon. Someone at
Qwest told me that the hosting server is not compatible with Vista. Is there
such a thing? I did not have this problem until I switched server hosts. I
can understand that they only handle incoming mail...but I'm wondering why I
didn't have this problem until I made the switch. It makes me think that is
playing some sort of part in this. Thanks for any help.
 
I'm not sure if the incoming host switch had anything to do with
your sending problem. Also, it is extremely unlikely that the
hosting server is not compatible with Vista.

There are two potential problems with your arrangement.
1. ISPs like Qwest tend to block port 25 connections to a
non-owned mail server.
2. The SMTP server may authenticate by looking at your IP,
and if it is not within their authorized IP range, they will deny the
connection. How does your SMTP server authenticate?
When you look at Tools > Accounts > select the account >
Properties, Servers, is "My server requires authentication"
checked, and if so, did you use custom settings instead of
the default (which is incoming server credentials).

I'm curious, why don't you use your ISP (Qwest) to send?

I would be able to diagnose your issue much better if you had included
an exact copy of the error message. If you reply, please include that
error message verbatim.

"Mainly, that the email cannot be relayed."

This would indicate that your hosting server is not recognizing that you are
"logged on".
It's a security measure on the server end to make sure that unauthorized use
is prohibited (hijacking of your account to send spam, etc).
You can change the settings in your account to log on before sending, or
sometimes just *checking* for new mail before attempting to send any will
open a window of opportunity (measured in minutes) to also send through your
server.
 
Thanks for your reply. I'm a "novice" so I will answer your questions the
best that I can.
#1 I know that changing the server host should not make a difference, but I
was fine until I did. Strange coincidence.
#2 I did some reading about the port 25 and changed the port to 26 is see
if that would make a difference, it didn't.
#3 The ISP does not require authentication...at least that is what the
Qwest techs told me...but I played around with it anyway...and changed the
settings in a multitude of ways hoping to stumble upon one that worked. It
didn't. Including stating that authentication was needed...to checking the
box for sercure (SSL).
#4 I went with Qwest DSL because we had phone lines in the building. We
don't have cable, so it would have cost $$$ to go that route. I suppose I
should have looked at a dish...or something, but I thought Qwest would
work....I use it at home with no problems. But now I am under contract for
two years.
#5 The main error code that I am getting is: Server Respone: 553
Relaying denied, Port 25 Secure (SSL) No, Server Error: 553 Error
0x800CCC79
#6 I read that maybe I should turn off the email scanning (Norton) that
maybe that was messing things up.
#7 I was also going to try Mozilla Thunderbird as my email program rather
than Vista Microsoft Mail...wondering if that would make a difference. I
thought I would send a test email out of Thunderbird to see if it would go
through.
#7 Yes, I am grasping at straws! Thanks one and all....
 
My comments are numbered to correspond with yours.

#2. You can't pick a port at random. You have to use one
that the SMTP server supports.

#3. I wasn't asking if the ISP required authentication, I asked if
the outgoing (SMTP) mail server required authentication.

#4. I didn't ask why you selected Qwest as your ISP, I asked
why don't you use Qwest to send (i.e. use their SMTP server).
Perhaps I'm misinterpreting your original statement where you
seem to be distinguishing between your outgoing server host
and your ISP.

#5. The error message is not complete. It doesn't identify
the server name. I need the SMTP server name.

#6. By all means, turn email scanning off, regardless of
whether it is causing this particular error or not.

#7. Using Thunderbird should make no difference with
respect to the error message you're getting.

#8. If you use (or can use) Qwest's outgoing mail server, take
a look at these directions:
