How to make a Negation Mail filter Rule

I have been trying to create a rule of negation in Proxmox Mail Gateway and nothing.

It turns out that I want to deny access or entry of messages containing more than 2 arrobas in the email address. With this regular expression I achieve it:

^ [a-zA-Z0-9 _.] + @ [a-zA-Z0-9 _.] + $

For example: (Matches) (Does not match)

But when I'm going to create a rule in the Mail Filter, I realize that I do not have the possibility to create a rule with content negation.

I have tried to create a regular expression with the denial of the aforementioned regex, but I have not succeeded, so it would be much easier to make such a negation rule on the PMG Mail Filter.

Sorry for my bad English.
