Hi, I wish to all mail that was sent by apache to be delivered with my domain, for example, instead of apache@mail.domain.com the mail should be delivered as apache@domain.com.

I did some approaches, but none of them worked:
1) I created an entry in /etc/postfix/generic and then executed the postmap command along with the "smtp_generic_maps = hash:/etc/postfix/generic" in main.cf file.
2) I created an alias to an existing account in my virtual domain, for example, "apache: postmaster" in /etc/aliases and also /etc/postfix/aliases.
3) I updated the postmaster account in LDAP with the shadowAddress attribute.

Does it have the fourth way? Or none of this are right to use with virtual mail?
