Email too short ??

Hi

Can someone help me ??

I like create a forum for a company I work for & register it to my work email address, but can't as my email is too short,, since it contains 4 letters then followed by @ $$$$.com, it's something like ' info@ghghgds.com'

Now, I don't really want to register it to my personal address as it'll belong to the company I work for so therefore by rights, it should be registered to work email address,, I have tried to change it on admin panel but it keeps saying 'email invalid'

So, can someone help me on how I can do it myself or do I need to contact someone to change it for me ??

Thx.
