Email address validation in GUI too strict

[GoogleCodeExporter]

Problems with validating email adresses:
django's email validating is to strict. (eg if quoted user part, space is not 
allowed).
use case: x400 via IPmail (x400 addresses are used in email-addresses).
Use re-expressions to get this better/confrom email standards.
