smtp.helo = changeme.com

[vmnetwork]

Hello
I set up a program Roundcube, everything works fine.
But sent emails worth parameter:

Authentication-Results: mxs.mail.ru; spf = none () smtp.mailfrom = [email protected] smtp.helo = changeme.com
Received: from xxxxx (port = xxx helo = changeme.com)

Where in the settings you can replace the entry "changeme.com"
