I need some help sorting out the exchange connectors on a server.
We were called in to figure out a spam problem. It's not severe and during our exam, we are trying to check the configuration of Exchange and get mail test tools to be happy.
Right now we are getting: Reverse DNS does not match SMTP Banner from mxtoolbox.
This is a simple MS Exchange setup; One Exchange server on a domain, people connecting with MS outlook from inside the building on the domain and from outside the building using Ms Outlook, and two copiers that can send e-mail.
The issue is all the receive connectors. It's not clear to me which one mxtoolbox is seeing.
Client Frontend EXCHANGE
Client Proxy EXCHANGE
Default Frontend EXCHANGE
Outbound Proxy Frontend EXCHANGE
I'd like to know what each one represents. ie; I presume Frontend mean Internet facing, but I'm not sure. Also, do internal MS Outlook users connect to a receive or send connector? (or both?)
