The title says it all. I have checked everything. I have AT&T DSL, i know my user name and password. At&t does require SSL, so I enabled that, I have the correct port # for outgoing messages. Everything seems to be find, the only concern I have is the host name. On the at&t site I linked below, it says the outgoing smtp is outbound.att.net . The book always reverences it as smtp.yourprovider.net and not that there could be a outgoing. in front of the provider. Regardless I get errors either way.

I changed my password and e-mail address for privacy reasons, but I checked both the incoming and outcoming several times, they re correct valid.

The error message in the browser leads me to believe that the smpt.outgoing.att.net is not correct. I have tried several variations,m including just using smpt.att.net or just outgoing.att.net with no .smpt in from of it, smpt.outgoing.yahoo.att.net and smpt.yahoo.att.net since the att tech guy initially had me log in to my att email via att.yahoo.com.

...help, please

now getting this error:
An existing connection was forcibly closed by the remote host

didn't really change anything. Tried a few different server address I found on the internet that I though may work. Even if you don't know the solution, if anyone could expliane any bit of this they do understand it would be greatful. This is the only area I've some across so far that the book does not give enough information about

It's SMTP, not SMPT. Simple Mail Transfer Protocol.

Yeah, I mis-typed in the bottom of my forum post...but if you look at my code you see i have smtp written everywhere it needs to be. So thanks for trying...I wish it were that easy, lol. But aside from the mistakes at the bottom of my forum post, I have combed the code for errors and can't find any....including putting smpt instead of smtp

This snippet from dump you included in the first post suggests otherwise:-

<system.net>
<mailSettings>
<smtp deliveryMethod="Network"
from="Brandon Grunwell &lt;[email protected]&gt;">
<network enableSsl="true" userName="[email protected]" password="correctpassword" port="465" host="smpt.outbound.att.net"/>
</smtp>
</mailSettings>
</system.net>

And a bit further down:-

Thanks for pointing that out...I thought u were just referring the my comments at the bottom where i put 'smpt" like 6 times, not the time in the code. I knew that was not the problem so I dis-missed it, but I appreciate you going through the code and finding that error. Even when i have smpt.outgoing.att.net it doesn't work. I had changed that value 1000 times before posting, 999 of them with smtp, so I knew that was not the problem . I have, however, found an SMTP server address that MIGHT work. when I use astp.att.yahoo.com I get this error in the web browser :

Server Error in '/' Application.

If anyone else finds typos besides the ones that were kindly pointed out, perhaps they are the issue. I don't know. My frustration level is high, sorry for the sloppy posts. I will tighten things up next time.

My brain hates the combination SMTP!! I would like to append my last message "Even when I have smtp.outgoing.att.net** the code does not work. I just worked over my code AGAIN, no smtp errors. I am left with the error:
An existing connection was forcibly closed by the remote host

Hi there,

The SMTP part of the server name used in the book is "just" an example, but one which is common for many mail servers. However, this is not a requirement and you'll find many mail servers that don't use this convention.

Your latest message seems to suggest that some server is listening to the address you're using, but doesn't allow you to connect to it, or doesn't allow you to use the port specified.

Do you have a Yahoo or Gmail account? If so, you can use that. You'll find an example for Gmail in the book.

Alternatively, if you just want to proceed with the book, you could also use a local drop folder as explained in Chapter 9.

Hope this helps,

Imar

I don't know for sure, but these settings look correct except for the server name, which I think should be "smtp.att.yahoo.com".

Thanks mmmason and Imar. Question for Imar: If I have a gmail account and and internet connection i can use that as an SMTP server? I am unfamiliar with networking completely, I for some reason was under the impression I had to use the e-mail from my ISP in order to have a server, or I had to set up something special with google for it to work. I had tried using my gmail e-mail, but not carefully, as i was unconvinced of its potential of success. But using the google outgoing port# 465 (according to a website I saw, same as at&t), my log in info , password, and smtp.google.com as the host, it should work? Is there not any issues with setting up a port number for the receiving e-mail address or anything like that?

Also, through another forum I was looking at, on a topic only somewhat similar, I saw something mentioned about the receiving e-mail server possibly recognizing SMTP as spam and not allowing the message through? Any truth to anything like that?

I know I can move on without completing this, but I just don't like leaving lose ends.

Thanks again
