Hello,

I have tried to register into AbanteCart for testing purposes using myAddress+test1@gmail.com but got a validation error. Looking up validation rules, I stumbled on this post, in which a core developer mentions that the validation regexp is:

define('EMAIL_REGEX_PATTERN','/^[A-Z0-9._%-]+@[A-Z0-9.-]{0,61}[A-Z0-9]\.[A-Z]{2,16}$/i');

This would explain why I get a validation error, but I am surprised the validation is not done with respect to the RFC, which you can look up on Wikipedia at the Email_address entry (I cannot post the link)...

Argument: the case for avoiding such addresses can be made since, in fact, it bypasses the 1 account per person rule. However, allowing such cases for testing purposes seems worthwhile. Also, validation imho should be just that: making sure the field has been validly populated. I regularly pest at websites which forbid me to use + in addresses because it is super practical for email classification. Therefore I would like it if my website were to avoid being in this category :-)

Questions: am I missing a setting anywhere? If not, should this become a feature in a future version? and in the meantime, how can I provide my own validation regexp?

Thanks! Tepp.
