Why does sendmail change address when sending?

Question

linux

When sending mail to [email protected]_domain.ru, it sends it to [email protected]_domain.ru with other domain addresses, no problem, what could be the problem?

#sendmail -bv [email protected]_domain.ru
->root... deliverable: mailer relay, host my_domain.ru., user [email protected]_domain.ru

#sendmail -bv [email protected]_domain.ru
->[email protected]_domain.ru... deliverable: mailer relay, host my_domain.ru., user [email protected]_domain.ru

I understand that this is an alias somewhere, but where? , there is nothing in virtusertable and mailertable.

Answer 1

/etc/alias looked?
