Question on SMTP mail.

[whloo]

Hi,

I am using smtp to send mail.
Wish to understand more how actually the smtp server work.

I use the below code to send mail without specifying the smtp server name and it works perfectly find.
It will auto detect my smtp server i presume....

public void sendMail(string xTo,string xCC,string xBCC,string xSubject,MailPriority xPriority,string xBody)
{
MailMessage xMailMessage = new MailMessage();
xMailMessage.From = xFrom;
xMailMessage.To = xTo;
xMailMessage.Cc = xCC;
xMailMessage.Bcc = xBCC;
xMailMessage.Subject = xSubject;
xMailMessage.Priority = xPriority;
xMailMessage.Body = xBody;

SmtpMail.Send(xMailMessage);
}

Then when i bring all my code to my home, surprisingly it able to send mail also using my application.
Now i wonder if the smtp is using my isp smtp server?
if anyone have better idea on how the SmtpMail work, please contribute as i wish to know more about how it actually work.
Thanks!

regards,
weihann.

you can specify your smtp server using the smtp class property (before you send the mail obviously):

System.Web.Mail.SmtpMail.SmtpServer = "smtp.yourserver.com"

you should specify the server you are using before you send mail. i do not know how it would automatically resolve your smtp server however.

hi hotwu,

i didn't specify it currently and i am pretty like the auto detect smtp server part.
just curious how it actually working.

this is just a guess, but perhaps your local computer has already registered default smtp servers to use with current e-mail applications. the .net framework may be able to detect these currently installed smtp services... or perhaps it is detecting ms smtp service running on your computer (if it is) ~ i know that this is definitely possible.

these are just a couple ideas, if i see anything online concerning this i will let you know.
