Hi,

I have a machine with many domains running on Apache WebServer, port 80.
Then, I read in Zimbra install manual that I don't have servers running in ports like 80 (web), 25 (smtp), etc. I didn't find an option in installer to configure another port for Zimbra webmail, and then the install really fail. And I can't stop Apache to install Zimbra at this moment.

Then, I thought the only solution for this is to install in night hours, to really stop Apache, install Zimbra, change webmail port with "zmprov ms ... zimbraMailPort 8081" command, and then restart Apache, right?
