With linq you can do it simply:

emailaddress = new String(emailaddress
                                     .Where(x=>x!=' ' && x!='\r' && x!='\n')
                                     .ToArray());

I didn't compare it with stringbuilder approaches, but is much more faster than string based approaches. Because it does not create many copy of strings (string is immutable and using it directly causes to dramatically memory and speed problems), so it's not going to use very big memory and not going to slow down the speed (except one extra pass through the string at first).
