• The APS Catalog has been deprecated and removed from all Plesk Obsidian versions.
    Applications already installed from the APS Catalog will continue working. However, Plesk will no longer provide support for APS applications.
  • Please be aware: with the Plesk Obsidian 18.0.78 release, the support for the ngx_pagespeed.so module will be deprecated and removed from the sw-nginx package.

Problem with SPF and DNS resolution

This issue is still persisting. There seem to be servers on the Internet that return a SERVFAIL when queried for the SPF RR. While I believe this is wrong (it should return NOERROR or NOTIMP), it does result in Plesk returning a tempfail for e-mail delivery.
The SPF RR is deprecated for some time now, and I feel the right thing to do is to remove the query for SPF RR and only use TXT RR.
