PTR Record

pkmeiner

I am currently trying to setup home mail servers for myself. I need to have my PTR record changed so that it connects to my FQDN of the mail server rather than the what it is linked to automatically by Spectrum.

Could anyone help me with how I would go about doing this?

Thank you.

Greetings Pkmeiner. Way cool you are exploring email server setup at home. There are lots of options to do so but it is not a service that Spectrum or most internet service provides offer or support on residential accounts.

Their are a variety of DNS record types in addition to PTR records that need to be configured for email including but not limited to CNAME, A records, MX records (mail exchange) , SPF records (sender policy frame work), DKIM records (domain key identified mail), DMARC (domain message authentication reporting and conformance) etc.

Similarly, static ip addresses are an element of reliable email config. Static IP are generally available on business accounts but not residential accounts. Some folks use Dynamic dns ( there are several flavors of dynamic dns 3rd party providers available) to address the lack of static ip issue.

If you do decide to use a 3rd party/non-Spectrum email - a quick summary of what is involved included below:

Great answer and content! Thanks!

One issue you'll run into trying to host a mail server, is that your IP will be listed in the Spamhaus ZEN blacklist, so you won't be able to send mail to any server that uses that as a blocker.

Another will be the lack of an rDNS entry.
