It would be possible to create an email sender that does not take in the application code the password and the user's credentials?
In particular I would like to create an email sender that leverages the method SmtpClient.SendAsync for not going to block the program when sending mail.

Well you could always include a few TextBoxes that ask for the user's account information instead of hard-coding it... that would be safer for sure.

If you mean sending mail without specifying any account information, I don't think that's possible at all with any of the major email providers.

So you're saying that some software companies that implement forms of assistance in their applications have added the credentials of their email in the software?
This would put at risk all the time.

I'm not sure I know what you're talking about... :?

Wrong #KraZy, they send the data ENCRYPTED to their web servers, which send the email; since the scripts are server-side, there is NO chance of leaking the source!

However, you can use SMTP, etc. (as #comathi correctly pointed out) to send validated and authenticated emails from your .NET application. Its pretty easy, too!

But, you CAN send email without giving ANY detail what-so-ever. You can spoof the "X-FROM" flag, which'll trick the system into thinking that its a valid email, however its not; most emails like this, are tagged "spam"; however there are other methods which you can use for that, but are miles away from the scope of this reply.

Any help? Skype: chris.harrison367 or PM me!

If you have your own web server I would upload information encrypted and decrypt it server side, use PHP to send the mail too. I dont think many businesses would use SMTP purely

I created an email sender who has access credentials in the code, but these credentials are encripted using an encryption key.
In addition, the code is obfuscated with smart assembler so if I haven't made the maximum protection, I still greatly hindered the possible hack, don't you think?

Good idea to encrypt and protect - nothing is 100% hack proof though.

You should also use a disposable email account then if it does get hacked you can just update your software with a new one and no harm done.
