If i use the escape char '_backslash_', it automatically strip it out when i save the field, why?

You're using regex as if it's "Forbidden words..". This is not how regex works, please review the information found here on regex usage.

I'm using this regular expression to match user's e-mail:
/^[a-zA-Z0-9._]+@[a-zA-Z0-9.-]+_backslash_.[a-zA-Z]{2,6}$/

Is it wrong?

Update:
Backslash is stripped here also, so i used _backslash_ here.

Your email regex appears correct, but it's highly dependent on what content the user is providing. For example the following emails will validate, but is clearly not valid with the regex you've provided.



You could use the following for example to remove consecutive periods in the domain.



However the following would still validate. It's simply a matter of trial and error until you've something satisfactory.



You could then add more checks to prevent consecutive periods AND dashes (dashes optional) using the following.

Thank you, anyway the problem is the same: the escape char "backslash" is removed when you save the field, why?

I don't know, if that's the case then simply encase in brackets as follows.
