Problem after change hostname

[li_zard]

When install ZCS 7.1.3 first time, I was make mistake with hostname, and have hostname=domain=myzimbra.net
but need to be hostname = mailer.myzimbra.net, and domain=myzimbra.net

Then I'm changed hostname:
zmsetservername -n mailer.myzimbra.net

Now it would seem all right, but stopped coming Daily Statistics to the zimbra@myzimbra.net
In the logs I see that the server tries to send the statistics with a non-existent addresses: zimbra@mailer.myzimbra.net to admin@mailer.myzimbra.net instead zimbra@myzimbra.net -> admin@myzimbra.net.
All other accounts, like user@myzimbra.net works fine.
How can I fix this, and rename zimbra@mailer.myzimbra.net to zimbra@myzimbra.net ?

Go to the wiki (link at the top of this page) and search for the article on changing the server name, follow the troubleshooting steps in there for details on what to do. You could also search the forums for details on how to make the required changes.

Thank You for the replay!

I'm read troubleshooting steps, do you mean problems with certificate ?
Now I recreated Self-Signed SSL Certificate with:

/opt/zimbra/bin/zmcertmgr createca -new
/opt/zimbra/bin/zmcertmgr createcrt -new -days 365
/opt/zimbra/bin/zmcertmgr deploycrt self
/opt/zimbra/bin/zmcertmgr deployca

And then restart zimbra

everything works as before. User accounts in order: user@myzimbra.net
but zimbra is trying to send mail with an incorrect address zimbra@mailer.myzimbra.net -> admin@mailer.myzimbra.net
