Sending mail via SMTP server

[iambenb]

Hi all

This is very frustrating. As far as I can tell my code should work.
Indeed, I have got something similar working using VBA (and the
CDO.Message object).

I get the error "The operation has timed out" so I think that it's not
connecting to the SMTP server at all. Anyone got ideas? Here's the
code:

<code>
MailMessage m = new MailMessage();
SmtpClient c = new SmtpClient();
c.DeliveryMetho d = SmtpDeliveryMet hod.Network;

// I've tried this with and without the domain
System.Net.Netw orkCredential cred = new
System.Net.Netw orkCredential(" SmtpUserName", "SmtpPassword") ;

c.EnableSsl = true;
c.UseDefaultCre dentials = false;
c.Host = "SmtpServer ";
c.Port = 465;
c.Credentials = cred;

m.To.Add(new MailAddress("so meone@mail.com" );
m.From = new MailAddress("fr om@mail.com");
m.Subject = "DotNet email";
m.Body = "Hi Ben" + Environment.New Line + "This email
was sent via code through SMTP";

c.Send(m);
</code>

I can't see anything wrong with that. If anyone wants me to post the
VBA code that does work, I will.
I'm thinking that I may have to use CDO, which I don't really want to
do.

Thanks,
Ben

I had problems with SMTP: mine were down to the virus checker blocking port
25; this cause stray error to be reported.

Thanks. I've definitely not got that problem, and in fact I can get
this working using System.Web.Mail . Microsoft tells me that I should
be using System.Net.Mail instead, but it doesn't work!!

Works for me with the same construction (other variable values, of
course, for server, username etc..)

But I did not see you supplied a "sender". If I leave that out, our
mailserver fortunately complains.

Does it work for you, if you also supply a sender to the message?

Try this....which allows "tweaking" in a much easier way.

There is a note about port 465 in the downloadable zip as well.
