[TYPO3] Confirmation emails of sr_feuser_register - Need help

[Andreas Balzer]

Hi,
The emails sent by sr_feuser_register look like these: "Of copy en paste 
deze in uw browser.<br/><br/>" The html code is not sent as 
html but as plain text. The option to send emails as html is enabled. 
Also this behaviour occurs on the actual website. For example: 
"<b>USERNAME IS HERE</b>"

What to do?

Greetings,
Andreas
