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.

It seems that there is an issues with your mail client setting, Please try to update SMTP authentication setting on your mail client and check this again.
