Heres the configuration section from my ASP script

        iconf.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
        iconf.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp.att.yahoo.com"
        iconf.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 465
        iconf.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 60
        iconf.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
    iconf.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = sUserName     
    iconf.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = sPassword
    iconf.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpusessl") = True

I can send messages fine with an ASP script.

When I configure DNN as follows, I get :

Failure sending mail. Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

SMTP server: smtp.att.yahoo.com:465

SMTP configuration: basic

SMTP enable SSL: checked

username and password entered same as ASP script

Am I properly putting in the nonstandard port 465?  Does DNN work with other ports besides 25?  What else could be going on here?

Thanks,

Mike

I have to go into the code of DNN to use a non-default port?

Am I the first user to try to use a non-standard port for sending mail?

Looks like it.  From a quick poke in the code, I don't see a SendUsing port set anywhwhere, so it assumes the default of 25.  Might be a good idea to post this in Gemini as a request.
