Topic: It's possible to use http for webmail instead https?

[linuxhelp]

Hello

is it possible to modify webmail to run with http://serverip/webmail?
(cause 443 is blocked by some company's proxys only the port 80 is opened)
how must i set it?

thanks for help

If you do this, the company running the proxy will harvest all of the usernames and passwords that are used to check webmail from behind their proxy.  Are you sure this is OK?

Are there any other ports that are open through this proxy other than port 80?  If they allow traffic on port 110 (pop3), for example, you might be able to setup a port forwarding rule on your SME from port 110 to port 443, then have your problem users access webmail at https://your-sme-server:110/webmail.

This way you wouldn't have to destroy the security of your server...
