Mailsrv_conf_init... not found, skipped

Hello Parallels Plesk forum,

I'm experiencing some issues using the plesk repair cli tools.

Linux:
CentOS 6.8

Plesk version:
Plesk Onyx
Version 17.0.17 Update #10

I'm trying to execute: plesk repair mail
But I receive this error: mchk failed: ==> Checking for: mailsrv_conf_init... not found

When I try to find the file it does find it... It seems like some configuration file is wrong?
...
