Chapter Nine: Must issue a STARTTLS

jwgc · September 20th, 2009, 08:06 AM

Hi Imar,

Thanks for the quick response. I got it to work now. It looks like it was a combination of setting my login credentials, turning my firewall off and not liking the EnableSsl.

Thanks for your help!

Hello Imar
This is my first post to the site and as other persons had faced problem the same I have. I can not send emails with the examples given in your book. Well I have found this book as "best of breed" but emailing is really bottleneck. I have used TRY & CATCH blocks as well as suggested in one of the posts. But I still have problem, it always executes the CATCH block.
Also please specify more that in code where to write "[email protected]" as it is, and where to replace it with the real data.
I use gmail account and my email Id is "[email protected]".
And also specify that should it need to be replaced

Code:

myMessage.From = new MailAddress("[email protected]", "Sender Name Here");
      myMessage.To.Add(new MailAddress("[email protected]", "Receiver Name Here"));

into relevant information or leave it as it is.

Please reply me as soon as possible as I have been dealing with this problem for last 6 days.

Hi Jack,

As indicated in the book, you *always* need to replace [email protected] with your own e-mail address; it's just a placeholder meant to refer to your own e-mail address.

If you're using a Gmail account, does that also mean you're using GMail's mail server? If so, did you try the code I posted earlier in this thread? You need to set the port number and set EnableSsl to true.

The problem with sending mail is that there are way too many different configurations so the book couldn't deal with them all. However, if you're using GMail's SMTP server the book's example should work.

If this doesn't help, can you post your exact code and the config section from web.config? Don't forget to replace your password and other sensitive data before you post here.

Cheers,

Imar

Heuh? Did you just post the same question again? If so, why? Or is that a forum bug?

hello sir, I have sent the code I used, please guide me regarding this.......

Imar · September 21st, 2009, 05:29 PM

Four things to try:

1. Make sure that in web.config you use vkhilaryjack @ gmail dot com (as one word / valid e-mail address, don't want to post your full address here) and not just vkhilaryjack. Gmail wants a full e-mail address.

2. Try the code I posted earlier that explicitly sets the Credentials property of the client.

3. Make sure you replace [email protected] as discussed earlier. I am pretty sure GMail requires you to supply a valid e-mail address.

4. Remove the Try/Catch block so you can see what the actual error is....
