How to send emails from your web application program running on protected hosts

[vit]

My task is very typical. I get an email from the user through the html form and need to send him a confirmation to his email address.
I tried it to do using sendmail and SMTP package but my web host provider server does not allow popular address like yahoo, gmail, etc to be sent protecting ftom malicious software.
So, please share your experience what you do to send emails to an arbitrary address.
How is it implemented in the forum software which send private emails, for example?

Hmm, maybe look into using Google mail API's (http://www.johnvey.com/features/gmailapi/)? I don't see one for PERL but you could use PHP and just call it from a PERL script?

Of course there is Perl API. See Email::Send::Gmail (http://search.cpan.org/perldoc?Email::Send::Gmail) on CPAN.

you could also use the perl SMTP module to use any server you like
