C:\Users\mfig>nslookup

Default Server:  x.local

Address:  10.70.1.201

> set query=TXT
> acme.com

Server:  x.local

Address:  10.70.1.201

 

Non-authoritative answer:

acme.com   text =

“MS=ms82793785”

acme.com   text =

“v=spf1 a mx a:acme.com ip4:x.x.241.90 ?all”

>exit

Manually lookup Records -MX record

There are plenty of commands for DNS server support.  Here’s the one specifically looking up the MX record…

set query=mx
> acme.com
Server: UnKnown
Address: 10.10.10.1

Non-authoritative answer:
acme.com MX preference = 10, mail exchanger = mail13.safesecureweb.com
> set query=mx
> acme.com
Server: UnKnown
Address: 10.10.10.1

Non-authoritative answer:
acme.com MX preference = 10, mail exchanger = mail13.safesecureweb.com

Bad MX Records for GoDaddy O365 Example:

acme.com MX preference = 0, mail exchanger = smtp.secureserver.net (needs to be removed)
acme.com MX preference = 10, mail exchanger = mx1-us1.ppe-hosted.com (these have higher priority and are fouling things up – remove)
acme.com MX preference = 20, mail exchanger = mx2-us1.ppe-hosted.com (these have higher priority and are fouling things up – remove)
acme.com MX preference = 0, mail exchanger = acme-com.mail.protection.outlook.com (keep this one)
acme.com MX preference = 10, mail exchanger = mailstore1.secureserver.net (needs to be removed)

Sender Permitted From or SPF

The most difficult one to add on certain DNS servers is SPF.  Edit Sender Permitted From entry in acme.com zone file.

Copy and paste into a notepad the SPF txt record…  “ v=spf1 a:dispatch-us.ppe-hosted.com include:spf.protection.outlook.com -all “ so you can correctly add the fields by doing a side by side comparison as displayed below.  Once the entry is saved, the SPF record should look exactly like the notepad.
