Issue:

Is there any way an Exchage email server could be used instead of Sendmail?

How to solve:

If the script runs in PHP, it will use the mail service configured in PHP, commonly sendmail or any other that behave like sendmail. Forms To Go creates a script in PHP, Perl or ASP and uses the mailserver commonly used by send email from that webserver.

In PHP and Perl, a script uses the mail server configured in the same server.

In Perl, it uses sendmail by default, but changing the "Sendmail Path" in the Perl Configuration, to the path of another application that works like Sendmail, the generated script by Forms To Go will succeed in sending the email. (common mailers like Qmail and Postfix in the Unix world emulates Sendmail behavior)

In ASP, you can select the Email component used to send the email. There are 3 options: CDONTs, which use the mail configured in the Windows web server and, ASPEMail and ASPMail, which can use any mailserver (Exchange, Sendmail, etc.) which you configure in the "SMTP Server" option.

In conclusion, the script generated by Forms To Go will use the mail server you commonly used to send email from any other script you'll have in your web server.
