Which ports does Merak use?

Each service is bound to an IP address and port number.

These can be changed if required, however, Merak's default ports conform to Internet standards are may be required by your ISP.

Most installations will work correctly with the defaults.

If you are using a Firewall you must open the ports for all the services you are using.

Warning - Merak's POP3 and IMAP run as one service so if you stop one, the other will also stop.

The same is true for IM and SIP.

You should also be aware that WebMail and FTP run under the Control Service. If you stop or restrict access to the Control Service your users may not be able to use WebMail or FTP.
