Zimbra redirect webmail http to https

After Zimbra mail server installed, webmail work on url

https://SERVER-HOSTNAME-HERE

If you access webmail with out HTTPS, it won’t work.

To set HTTP to redirect to HTTPS, login to server as root, switch to user zimbra

su - zimbra

Run

zmprov ms SERVER_HOSTNAME_HERE zimbraReverseProxyMailMode redirect

Wait few minutes, HTTP link will redirect to HTTPS.

[root@correo ~]# netstat -lntp | grep 80
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      22891/java

You need to wait few minutes before it can start working on HTTPS port, no restart required.

Now netstat shows nginx runs on port 80

[root@correo ~]# netstat -lntp| grep 80
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      90391/nginx: master
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      22891/java
tcp6       0      0 :::7780                 :::*                    LISTEN      24005/httpd
[root@correo ~]#
