Question

The GMS install process currently tries to disable SendMail, PostFix etc. however I have a system that Sendmail is not currently installed on. The installation process still forces me to say YES to disabling SendMail which of course fails further into the install dialog since SendMail is not installed.

Answer

We have now changed the install process for UNIX boxes to disable the forced uninstall of SendMail.

The install now checks with the installer to see if other mail server software is running on this machine and to alert them that it may need to be disabled. If there is another mail server running on this machine, the installer is given the options YES to disable it or NO
to continue. In addition to correcting the forced uninstall of SendMail, this also allows for more than one mail server on the machine as GMS can be instructed to bind to only certain ports on certain IPs. This makes it possible to run GLWebMail or GLCommunicator in conjunction with an existing mail server. For example GLWebMail could be used in conjunction with SendMail and some other Pop/Imap server to extend the functionality available to users of the system.

There are 3 types of connection handling methods available through the GUI at Incoming>Connections. Options 2 and 3 below offer the flexibility needed to allow the smooth functioning of more than one mail server on a single machine.

Option 1 – Use only IP address
This is the simplest form to use, each full domain that you set up will require to have an IP address available to it. All the NTMail Services will respond using the default ports and the IP addresses defined on your network interface card and associated with the domain. There is no configuration option available for this selection.

Option 2 – Use specified IP addresses
This is somewhat of a halfway house allowing a degree of flexibility in the configuration of IP addresses and ports for services to respond on. Each full domain that you set up will require a free IP address on your system in order that the default options may be set up for it, however once set up you may amend these options on a per IP basis. Domains will only bind to the IP addresses that are configured against them.

Option 3 – Use IP Connection file
This third and final option provides full flexibility over how your server is set up. You have complete control over which service responds on which IP address and what port it listens on. It is not necessary to have a free IP address on your system to add a second or subsequent domain as each could share the same IP but listen on different ports. Each time you set up a domain or enable an additional service you will need to visit here to enable the connections options for the domain. Services will only bind to the IP addresses that are configured against them.

We also offer an option during the installation to select a non standard port for the SMTP service to enable ease of use with other mail servers.
