[NTG-context] e-mail - link in pdf not correct with dot in e-mail adress

Hallo group, an e-mail adress typeset with Context produces a clickable link in the resulting pdf file. Whenever I typeset an e-mail-adress of the form xxx.yyy@host.com, then the resulting link in the pdf-file just directs to the (non-existing) adress yyy@host.com. I tried to put brackets {} around the adress, to use \useURL or to put \setupinteraction[state=stop] to prohibit a wrong link but it did not work. (I'm using ConTeXt - 2006.10.24 13:47 and pdfeTeX-1.30.4) Is this a problem of setting the right command or using the right version? What should I do either to produce a correct or no link at all? Thanks in advance, Ole
