I have a client that wants to provide a security reporting tool to ppl who visit his web site.
It reads several settings on the users computer and makes the report (I've already written this part).

The user hits a button to send the report to my client in an email (must be in the body).
Sending the Email is transparent to the user.

It sounds like I need to use Winsock, but I'm open to any method that will do the job.

Problems:
1. Needs to run on Win95+ and WinNT4+ with any email client.
2. The reports can be 10,000 characters long and may have HTML structures in them.
3. Using Winsock, we lose the email if the user ISP/Mail Server uses SMTP authentication. (EHLO)
4. He has his own mail servers but they use SMTP authentication. He's unwilling to set a proxy host without the authentication.
5. I could write the authentication encoder just for his mail servers as long as I know exactly what they want. But I can't write code that can get through every type of SMTP authentication.
6. He doesn't want to use a 3rd party OCX/DLL

I suggested that we use his server and setup some dummy email accounts.
Then have the program use those accounts to send the email to him.
He doesn't want to use the dummies.

Main Question:
Is there a way I can use a client's server to send email to him without the user having an email account on his server?

Alternate Question:
If not, then how can I email these reports to him?
