RegEx - Not ending with certain suffixes

I want to validate a form input with an email address. I already have a RegEx for checking that it ends with certain suffixes (^.+@((gmail\.com)|(hotmail\.fr))$). Now, I would like to validate the opposite.

How can I match an email address that does not end with certain suffixes with a RegEx?

Edit: I'm using jQuery validate with unobtrusive validation, e.g.:

<input id="auth_email" name="auth_email" type="email" 
       data-rule-pattern="^.+@((gmail\.com)|(hotmail\.fr))$"
       data-msg-pattern="The email address must not end with '@gmail.com' or '@hotmail.fr'"
       class="form-control" required  data-lpignore="true">

I would really prefer a pure RegEx solution.

Yon use negative lookahead `^(?!.+\.(?:gmail|example)\.com$).+` – anubhava Jun 18 '18 at 10:28

`if (!/.../.test(input))` – melpomene Jun 18 '18 at 10:29
Why do you need the negative case? Is there some reason why a whitelist is less workable than a blacklist? – Tim Biegeleisen Jun 18 '18 at 10:29
You just need to negate the result using `!` or `===false` – Liam Jun 18 '18 at 10:30
@melpomene: I'm using unobtrusive validation with jQuery validate. See edit for more info. – Julien Poulin Jun 18 '18 at 11:41

Nevermind, I was able to make it work thanks to @anubhava' comment. – Julien Poulin Jun 18 '18 at 12:18
