SMTP sending e-mail

[John J. Hughes II]

I have an application that sends simple e-mails using SMTP, it no longer
works with a lot of e-mail servers.

Basically the problem seems to be that I am no longer sending a valid logon
sequence. The server says the user is not authorized, if I switch to
Outlook it works.

Code to send authorizion.

this.SendData(" AUTH LOGIN" + CRLF);
string user =
Convert.ToBase6 4String(System. Text.ASCIIEncod ing.ASCII.GetBy tes(this.User)) ;
this.SendData(u ser + CRLF);
string pw =
Convert.ToBase6 4String(System. Text.ASCIIEncod ing.ASCII.GetBy tes(this.Passwo rd));
result = this.SendData(p w + CRLF);
if(result.Start sWith("235"))
break;

This is what outlook is doing per the log file:

[tx] AUTH NTLM
<rx> 334 NTLM supported
[tx] TlRM.....
Any one know how to send NTLM type logon or another methed to work around
this problem?

Regards,
John

http://curl.netmirror.org/rfc/ntlm.html looks like a good starting point.

Any reason for not using the System.Web.Mail class that is part of the .NET
framework ? The fields property (with 1.1) allows to define how you'll
access to the SMTP server :

Patrice,

Thanks for the lead...

I would perfer to use the System.Web.Mail and that is what I used in the
first place. I recall running into a problem if IIS was not installed since
it use that or something.

Oh well I have tried again and am getting this error, any suggestion?

Error:Could not access 'CDO.Message' object.

Yes, you need to install the SMTP service first (IMO this service doesn't
require IIS itself).
