That's a good idea, except when you have to deal with companies like
Everbridge Inc or Tencent QQ, which apparently think it's a good idea
to
rent VMs at various cloud providers and run them with their default
config.
Amazon SES does not use email servers with PTR records that end with
compute-1.amazonaws.com, so it is not affected.
ec2-<ip>.compute-1.amazonaws.com is the default name of AWS instances
and only used where the owner did not specify his own domain. This is
akin to people sending emails from @...onmicrosoft.com or
@...azurewebsites.net or @...vps.ovh.<tld>
My mail server for domain simplemail.co.in has a ptr with the azure
domain as value:
$ dig mx.simplemail.co.in +short
20.120.225.36
$ dig -x 20.120.225.36 +short
tls-mail.westus2.cloudapp.azure.com.
do you think if I should change the ptr value to something other like my
own domain?
Thanks.
