Config Required For Email Flow, Config required for email flow

[Andy]

The only way I can see to create the setup as outlined on the following link is by having 2 seperate installs of xmail - one for the smtp relay and one for the mail server. Please can someone confirm if this is the case or whether I can accomplish it with only one install. I am told that it can be done using exchange just by adding a second smtp listener.

It seems over-complicated but I am being told that it is the proper way to set it up.

Thanks

Right. One in the DMZ and one behind. If you would handle this with a single instance, then the DMZ would make no sense for the SMTP service ....

I only have 1 server - so not sure about running 2 instances of xmail - can't see any problems other than the registry entries and the service.

I am questioning my setup (although it is working fine) because the assp people say it's not a good idea for users (email clients) to connect direct to assp. But cause I only have the one server I am best leaving my setup as is?

Never change a running system :-)

Build a DMZ should require more than 1 server. You might do the same with a multi homed host, but if a service is hacked the intruder can get a root shell to that machine passing by the DMZ.

So IMHO it makes no sense to build this on a single server.

Thanks for your thoughts.

The assp chaps arguments for doing this is not really cause of the DMZ but cause a server connecting to assp is far more tolerant of connection delays than mail clients (MUAs) or users i.e. they don't recommend that the users connect direct to assp. See

I think I will have to leave it is setup as is for now.

Thanks

I see ... if DMZ plays no role, and your config has been running smoothless, you should not change it.
