Having a issue with smtp client exception message in sms2cell app

sam

Hi guys Im new to the forum and C# and the world of programming :) ,

I came across this the tutorial: (C# SMS App which can be found here: http://www.c-sharpcorner.com/uploadfile/scottlysle/textmsgtocellphone12112006002339am/textmsgtocellphone.aspx )

I found it really fun to do so I started cracking at the code. When I downloaded the zip file, opened it and filled in the correct info to test send a SMS I got this issue which I have been trying left and right to solve...so far what Im guessing is that the program doesnt have a smtp server to bounce off of and it is currently using (or trying to) my machine to send the sms. I have tried defining a smtp server and also including a login credential statement to be true and even changed the port but still no help and get the same exception message:

any help would be greatly appreciated thank you all.

I have attached the source code file for the main and the only code I have adjusted is for the btnSend click event

Sam: You need to have access to an SMTP server that will allow you to relay email. Outside of work settings, this is getting to be harder to find (for free anyway); you might look into sending the message through a gmail account - I believe that is possible but maybe not through the free account. Else you might search for other sources that will permit you to relay through an existing SMTP server.

ok i got it to work thanks for pointing me in the right direction! Turns out free smtp relay server's are blacklisted by ISP's and the the only outgoing smtp servers allowed are the ones from the ISP's themselves

so all i would have to do is enter a "free smtp server" in the mail server box on the form and that would do the trick?
