email using smtp.gmail.com

i think my network didint allow me to use port..

 
 Junaid,
 
 Check with your network firewall team, might blocking the gmail port.

Interesting I tried 2 smtp servers and noone worked for me :(
Did someone else works it too ?

You say that you are 110% sure that your account parameters are correct. It is the extra 10% that is the problem. You are over-confident and insist upon ignoring the problem. I tried your code, and the only thing I changed are the parameters. I changed the from and to email addresses and the account name and password. Your code works for me. Your code sent a message to me. So please remove that extra 10% of certainty and look again at your parameters.

I'm 110% sure that my account parametrs is correct.
And I have the same error like this dude.
So maybe someone have good solution for this ?
With example code ?

Janis, are you able to send email using your email client configured to send through gmail that you usuallly use to send email? If you can, then you know that gmail is not blocking all requests. Are you sure that the account name and password are correct?

When I ping smtp.gmail.com the IP address is 74.125.155.109 but your error message says 74.125.115.109. I don't know why that is and if it is an indication of a problem. I think the problem is more likely that you have an incorrect parameter, such as (perhaps) the account name or password.

Are you serious?  you want to use gmail's smtp to send your emails, YOU CANT DO THAT they do NOT let you don't even bother trying.

It it possible that gmail is blocking incoming connection ?
I tried out few sources noone let to connect to server.

///THIS is a error sam

error occured unable to connec to remote server in exception?

You are using ex.ToString() and that is better since it will show ex.Message plus more.
 
Can you show the complete and accurate error message? That will help, except it might be a problem if it is not in English. Also look at the articles in this web site; I see one in the list at the right side of this window that is specifically about sending gmail.

What is the error in catch ?
Try write this MessageBox.Show(ex.Message);
Don't you need to show the username and password for connection ?
