Home Server PTR Record?
I tried a generic cloudron install on a Virtualbox guest OS on my home computer, just for testing. DO as domain provider, DNS API configured and cloudron up and running. Tried to activate email, but cloudron complain about PTR record, as it expects "my.domain.tld" but get my internet provider instead in the format of
My virtualbox cloudron server is configured with hostname "my.domain.tld"
How do I get/configure correct PTR Record on such an home server internet connection?
@stoccafisso Call your ISP and ask them to activate your PTR. tell them that the PTR needs to report to the EXTERNAL IP address of your cloudron install. Once that is done, it can take up to 48 hours for the changes to take affect.
@murgero thank you. I'll try that.
@stoccafisso I'd like to point out, some ISP's don't allow in/out SMTP so even setting the PTR, it might not work properly. Talk with your ISP about sending email and such.

Just to close out this discussion: most ISPs block port 25. Even incoming port 25 (this is true with comcast in the bay area). If this is the case, it's not possible to setup a home email server without some sort of a VPN/tunneling setup (like maybe Cloudflare argo). This is a bit outside the scope of Cloudron at this point.
@girish Just as a quick add-on, if you have Comcast business class, port 25 may be allowed by calling the business support line. Same with ATT.
