I have had a few customers call me and complain that the email validation on the checkout page is coming up with errors. Most of these customers have a "." or a "-" or some other non-standard (though valid) character in their e-mail addresses. Quite often, when I type them in for them it goes through correctly.
Is there some combination of browser version <-> email address that might be causing the problem?
What characters are valid as far as e-junkie is concerned in an address?
Thanks
