Changing Webmail HTTPS Port not working

Hello all.

I've been trying to change the webmail HTTPS port from 444 to 488 and I'm not able to.

I've executed the following command:

Code:

---

su - zimbra
zmprov -v ms myserver.com zimbraMailSSLPort 488
zmcontrol restart

---

without success. :(

I've tried several other changes but also without success.

One try was also to cancel the HTTPS access as follows:

Code:

---

[zimbra@vela ~]$ zmtlsctl http
Setting ldap config zimbraMailMode http for myserver.com...done.
Rewriting config files for cyrus-sasl, webxml and mailboxd...failed.

---

However but this didn't worked also.

Executed the fixpermission script and tried again without success.

Any help from here?

Thanks in advance.

My best regards,
Jose Barros
