OK, so what do they do and what are they for?
I thought I knew but today I had a weird problem.
We have 1 lotus server at my location and 1 lotus server at a remote location. There was a connection "file" that was set on the remote server to send all smtp email to a symantec antivirus gateway.
We cleared out the IP address of that server and then the email was being passed from the remote lotus server to the lotus server at this location.
NOW - that continued for a while and I posted this in the lotus section.
I started looking through our dns and found that there was only an mx record for the lotus server at our site. Thinking that the reason the remote email server was sending its email to our server which then passed it onto the pix and out because it only knew about the one email server with the mx record I added in an mx record for the remote lotus server.
Now the email started going right out to the internet from the remote lotus server which is what we wanted.
HOWEVER, to prove the mx record fixed the problem, we deleted it and rebooted everything and the email is still going directly through the PIX.
So, it appears the mx record did nothing to hurt or help.
so where in lotus does it say what and how it will send the email to and do I need that mx record.
