Validation doesn't work

Yeah it really is I didn't extend or change anything in any core class, I only use my own controllers, views and 2 own libraries. How the server configuration differs is difficult to say, because it is a managed server. I only know that it runs an Apache 2 with PHP4 (which I changed to PHP5 via CGI). The strangest thing is, that this really only happens if the email field is involved, have several other forms and those work perfectly (with form_validation). The parser is used in allmost every function (even in the other forms which works) so I can't imagine that this could be the problem. I don't know ... in the worst case I have to validate manual on this server in this function ... but it would be much better if everything would work the same way on every server

I really have no idea what it otherwise could be (your geuessings were good!) ...
