bad fqdn only on webmail access

[Gaarby]

Hi

I'm upgrading ZCS Network edition to v5.0.15 from 5.0.8 and changing of server
I have change the hostname. All works fine except webmail acces. When i tried to access via http or http , I have the login page and after i'm redirect to the old hostname.
Any idear, I think about of misconfiguration of servername in web server.
I don't know what's webserver is used by zimbra (tomcat, apache?)

Thanks for any suggestions

Welcome to the forums

How did you go about changing the server hostname ?

Thanks for your answer

I have follow this doc ZmSetServerName - Zimbra :: Wiki
su - zimbra
zmcontrol stop
/opt/zimbra/libexec/zmsetservername NEW_HOSTNAME

After I have modify /etc/hosts /etc/hostname DNS server

I have do a lot of grep on most conf files searching the old hostname but without any success

Did you check these aswell ?

zmprov gacf | grep oldhostname
zmprov gs `zmhostname` | grep oldhostname
zmlocalconfig | grep oldhostname
