Regex validation

[VamVan <vamseevan@xxxxxxxxx>]

Hello Team of Nerds,

I need help in writing a regular expression for this:

invalid character set is:

INVALID_STRING={"/","*","+","(",")","'\'","<",">",",",":",";","~","..",".@","@."};

I want to a pregmatch for these characters on my whole email address and if
match is found I need to return false.

Thank you
