Hello,
i've got the following problem: everything with this extension works fine except the mail-delivery of the form! I tried every configuration, from PHP Mail to Sendmail to SMTP, nothing works! In all cases, if i try to send the form, I get the following error messages:

PHP Mail: could not instantiate mail function
Sendmail: failed to open /usr/sbin/sendmail
SMTP: SMTP connection failed

I testet this on another server, there it's working! I also tried to disable the jNews component, no success!
I also checked the configuration of my server, I'm on hosteurope!

Adding a new Joomla User and getting a welcom email also works!

I really don't know what to do now, espacially while it's working on the other server! Can anybody help me?
