I have the following code and I'm unsure if I'm over-setting variables, or whether I am on the right track:

Code:

// Add an SMTP Server for each MX Server found

foreach (string smtpServer in mxDomains)

    mailer.SmtpServers.Add(new SmtpServer(smtpServer));

mailer.DirectSendDefaults.HelloDomain = mxServer;

mailer.DirectSendDefaults.LocalEndPoint = new IPEndPoint(serverIP, 0);

I then do a

Code:

mailer.Connect();

and

Code:

mailer.Hello();

after I've run through this configuration. What I'm unsure about is, am I actually using the

Code:

mailer.DirectSendDefaults.HelloDomain

in the Hello method, or should I be allocating this to the SmtpServer's HelloDomain?

When you're populating SmtpServers collection, direct send won't be used (unless all SMTP servers have been tried with no luck).

If you're emulating direct send manually (populating SmtpServers collection with MX servers), you'll need to set the corresponding properties (LocalEndPoint and HelloDomain) of SmtpServer object you're adding.

Regards,
Alex

Excellent. Thank you. That explains why my process is failing, since I'm sending out one IP and then it's resolving to a local IP and I'm getting disconnected.

Yes, the problem was in DirectSend...
