How to use nslookup command to check email domains in fedora Linux?
I used the following command in terminal:
nslookup -query=mx com3263@dcs.ruh.ac.lk
This is not working for me. What’s the correct command?
You can query for the domain part, not the full email address.
For programmatic use,
dig +shortor some versions ofhosthave better, machine-readable output thannslookup.Not all domains supply an explicit MX record; fall back to the A record in that case (i.e. attempt to connect directly to the host).
