regexp
 

Condition "OR" is represented with "|".
How I make command "AND" with regexp? Or either to enter in the necessary filter to have all the parametros in any place in the body of the email.

A logical and is usually performed by multiple stages. For example:

grep "PARAM1" | grep "STOP" | grep "PARAM2"

That is, in order to make it to the successive stages, the requirements of the preceding stages must have been satisfied.

These parameters are for rejecting email in postfix.
/etc/postfix/body_checkes

grep in regexp?

Sorry, your question was on regular expressions, not postfix configuration. Perhaps someone familiar with postfix filtering can address this...

Ummm ... if they come in the same sequence I don't
see the problem ...

the problem is that the necessary message is orderly.
example:

It functions perfectly!


But if I to modify the message it stops:
It does not go to function

In that case you will have to bite the bullet and do something
very ugly (if the repeated greps are not an option):
This would (quite obviously) become very verbose with more parameters,
so a repeated grep is probably the better choice.
