On the latest version of eXtender Enterprise for GP 2010 the email address can be up to 255 characters.
What about for 2013? And not the enterprise version but the "lite" version?
I just looked on GP 2013 and the email field allows 255 characters on both the Standard and Enterprise versions of Extender.
Extender 2013 is not yet available, it should be released sometime in mid to late February.
