What do you dislike about hosts Zimbra?

Question

Zimbra

zimbra does not want to install
ERROR: Installation can not proceeed. Please fix your /etc/hosts file to contain:
127.0.0.1 localhost.localdomain localhost
37.46.132.81 mtamail.mymailsmta.ru mtamail
Actually a hackneyed topic on the net about Zimbra - everything seems to be done correctly, does not go any further.

Answer 1

Why exactly 3 items per line? Goes essentially IP then pressing the tab and the name of the domain

127.0.0.1    localhost.localdomain
127.0.0.1    localhost
37.46.132.81    mtamail.mymailsmta.ru
37.46.132.81    mtamail

Answer 2

For 127.0.0.1, it should be set to localhost.localdomain localhost
For the server IP address, mtamail.mymailsmta.ru mtamail
Exactly, and nothing else.
In addition, if the Zimbra server will be used as MX, there should be a DNS entry about this.
The installer checks it a little later, but (unlike /etc/hosts) this item can be skipped.
