Im trying to add some functions to the survey mail. My trouble are that the mail received in gmail stacks every sent survey. This is no good. I also want the mail to add the mail address and from name of the sender. Another problem is that the survey name don't add to the subject in a mail. It only says Filled Survey at the moment.
Tried several things tonight, and this is the code i am at now.

{set-block scope=root variable=subject}{$node.name}{/set-block}


{set-block scope=root variable=from}Paal{/set-block}


{set-block scope=root variable=reply_to}paal@messenlien.com{/set-block}

Have not started to extract mail information yet.
Not sure why the set-block variable wont work here. Have used that in templates before.
Any suggestions or help out there?

Thanks, got it solved by changing the datatype file

                       $templateResult = $tpl_email->fetch( 'design:survey/mail.tpl' );


                       $subject = $tpl_email->variable( 'subject' );


                                                $emailSender = $tpl_email->variable( 'from' );


                       $mail = new eZMail();


                       $ini = eZINI::instance();


//                       $emailSender = $ini->variable( 'MailSettings', 'EmailSender' );


//                       if ( !$emailSender )


//                           $emailSender = $ini->variable( 'MailSettings', 'AdminEmail' );


                       $mail->setSenderText( $emailSender );                                        


                       $mail->setReceiver( $mailTo );


                       $mail->setSubject( $subject );


                       $mail->setBody( $templateResult );

And the mail template code

{def $timestamp=currentdate()}


{def $sender = = ezini( 'MailSettings', 'AdminEmail', 'site.ini' )}


{set-block scope=root variable=subject}[{$timestamp|l10n( 'shortdatetime' )}-{$survey.id}]{$node.name}{/set-block}


{foreach $survey_questions as $question}


        {switch match=$question.type}


                {case match='EmailEntry'}


                        {set $sender = $question.answer}


                {/case}


        {/switch}       


{/foreach}


{set-block scope=root variable=from}{$sender}{/set-block}


{"The following information was collected as the result of the survey:"|i18n('survey')}


<br>


{section var=question loop=$survey_questions}


{survey_question_result_gui view=mail question=$question}


{/section}

I have also made some template changes so the mail is being sent as html so the mail result is more understanding.
Can upload it as a hack project for the extension if someone need it.
