Lets see what are the Public DNS records we need to Configure for Exchange 2013/Exchange 2016 (Client Access / mail flow / Autodiscover)
Create A record – Mail.CareExchange.in
and point to the Exchange 2013 Server or Exchange 2016 Server .
If the server is load balanced – You will have to point to the VIP (Virtual IP of the load balancer)
Which will be the internet facing server for your Webmail and all other URLs
Create a A Record – autodiscover.careexchange.in
and point to the Exchange 2013 Server or Exchange 2016 Server .
If the server is load balanced – You will have to point to the VIP (Virtual IP of the load balancer)
Which will be the internet facing server for your Webmail and all other URLs
Which will serve your outlook and Active Sync phones to send configuration settings automatically.
Create a MX record – and point to the A record you created above for small businesses
Which will serve your mail flow
if you are going to use any Cloud based anti – spam or Anti-Spam Appliances . you will have to point it to their DNS Records or your Anti-spam Appliances.
Required Public IPs – 1
Required Public IPs with One Anti-Spam Server – 2
Ports need to be Opened on the firewall
Ports for HTTPS – 443
Port for Mail flow – 25
POP3 – port 110
IMAP – port 143
SMTP – port 25
HTTP – port 80
Secure IMAP (IMAP4-SSL) – port 585
IMAP4 over SSL (IMAPS) – port 993
Secure POP3 (SSL-POP) – port 995
Secure SMTP (SSMTP) – port 465 | Exchange specifically does not support SMTPS (implicit TLS)
Updated – Download as Excel Sheet
Note :
If you want to Split Mail flow and Outlook Web App URL. you can also do that .
You can have outlook web app and other URL’s has mail.careexchange.in
and for mail flow you can have mx.careexchange.in
by doing this – the advantage you can re route your mail flow anytime without disturbing anything .
For Reference :
Lets see a practical scenario on create DNS records with one of the public DNS providers
HOST A records – mail.testcareexchange.biz
HOST A records – autodiscover.careexchange.biz
MX Records – Testcareexchange.biz
Note : Mail is delivered to the mail exchange server with the lowest preference number (highest priority)
