  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Problems with Freenet and DNS PTR record

Hello,

Today I got in trouble with Freenet. I tried to send an e-mail to a recipient at freenet.de and got the following:

This is the mail system at host blah-blub.de.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

The mail system

<[email protected]>: host mx.freenet.de[2001:748:100:40::8:110] said:
550-inconsistent or no DNS PTR record for xxxx:xxxx:xxxx:xxxx::xxxx:xxxx (see
RFC 550 1912 2.1) (in reply to RCPT TO command)
Click to expand...

That's funny because all other mail-servers accept my DNS config. Just Freenet didn't. So I had a look into Plesk and found the default abbreviation <ipv6> for my PTR record. Which resolved to xxxx:xxxx:xxxx:xxxx:0:0:xxxx:xxxx of the provider config. This was not accepted by Freenet. They obviously accept only the condensed version.

To solve this I replaced the <ipv6> placeholder by hardcoded xxxx:xxxx:xxxx:xxxx::xxxx:xxxx. And this works.

Who does now the mistake? My provider? Plesk? Freenet? Charly Sheen?

Kind Regards
Hans
