I have exim on server №1 (1.1.1.1). A mailbox info
was created, and email was sending and receiving successfully. But when I perform sending from server №2 (2.2.2.2), using an email and password for authentication, the mail server does not let me, giving the following error:
H=mailer.server2.com (1.1.1.1) [2.2.2.2] rejected MAIL : Access denied - Invalid HELO name (See RFC2821 4.1.3)
How can I adjust the resolution to be sent from any server with any HELO №2 (2.2.2.2)?
Ubuntu was installed on all servers.
