[TYPO3-seminars] HTML-Mail

[Hoge]

Hello,

I would like to send the notification-mails to the attendees as HTML-Mails and don't get this to work

I'm using onetimeaccount for the registraion 
and installed also direct_mail to show the HTML-Mail-Checkbox in the registration form of onetimeaccount

but by checking this no entry is made and the notification-mails are always send in plain text

has anyone an idea for me how I get this work?

Thanks a lot

Hoge
