The second charset: [0-9a-z-\.] has an errant hyphen (-). In this case
the hyphen should be the first or last character. Also, the . char loses
its meaning inside square brackets, so you don't need to escape it.
Eg: [0-9a-z.-]

I did change the comment to what you suggested:
if (eregi(^@([0-9a-z][0-9a-z-.]+)\.([a-z]{2,3})), $website)){ // not a
link
but this seams not to work as well. It is still possible to post a website
like this: http://website
So somehow the last part does not work checking for dot and 2 or 3 char.
does somebody have an idea on that?
Thanx, Andy

For one thing, your regex doesn't match any definition of website
address that I've ever seen.
Look up the spec for URLs at http://www.w3.org/Addressing/ .
In the very least, you should not arbitrarily exclude valid domains just
because the last part is not 2 or 3 characters - what about .info,
.museum, etc.? And what's the for?
As for your error, I'd guess it's because you wrote [0-9a-z-\.] rather
than [0-9a-z\-\.] (escaping the -).
