MX/DNS records
Hi All,
I've taken over a new client’s IT – There DNS records are shown in the screen shot attached– the last IT guy seems to have duplicated MX records and has a unnecessary A record … information on this All virtual directories in exchange 2013 have “remote” and also OutlookAnyWhere has “remote” eg: https://remote.domainname.co.uk/
looking at my DNS Picture is it safe to say for MX records I can remove both the “remote” MX records that point to my web-filtering service as there is already MX records point to the web-filtering service already?
Also there is a “mail” A record but my exchange 2013 does not have this configured for virtual directories – could this be removed?? Im assuming I need to keep the “remote” A record as I am using this for my exchange directories..

hi Arnold,
I can confirm they have only 1 exchange server but not sure why he has added the remote as they do not have no email addresses that have @remote.domain.co.uk

Those can be aliases for each domain.
It is a speculation on my part. You can remove the remote if you are certain. That might have been setup as a test to transition from one MX provider to another.
Do you have access to the 3rd party filter provider to see where the remote.mydomain.com points to within their system/interface?

im 100% certain - I spoke to the client they do not use no email address @remote.domainname.co.uk
im going to change the 3rd party filter provider and also only have it pointing to @domainname.co.uk - so emails will hit this then to my internal server...
Can I remove the "mail" A record? as I am only using "remote" in my exchange directory? am I correct in saying that for example if no MX records where present and as I have my exchange setup as "remote" for directories then this picks up from the "remote" A record IP into my internal server

All works fine now - previous IT company n guy had incorrect dns records :)
From the glance I think the setup is everyone in the firm has an email user@mydomain.com that is routed through a filtering resource that then delivers presumably to the internal exchange server.
Some mailboxes/aliases/distribu
The likely reason that both are being sent through the external processor is just in case the remote based email leaks out by the remote users.
Before making any external records, my recommendation is to use the exchange traces and the configuration of exchange to determine what is going on.
Is there another exchange server that serves the remote.mydomain.com if not present on the exchange?
