• Our team is looking to connect with folks who use email services provided by Plesk, or a premium service. If you'd like to be part of the discovery process and share your experiences, we invite you to complete this short screening survey.

  • 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.

    Issue ip=[]. Warning: Failed to parse return-path header

    Seen this before and didn't look into it, but it seems to be appearing more often now. Is this normal, or if not, what should I do? The blank IP concerns me most. Typical line looks like this: dovecot: service=lda, user=(redacted), ip=[]. Warning: Failed to parse return-path header

    Question log viewer search by date? or load more at one time?

    I'm trying to see logs from around noon yesterday, but the date selection is only "from" with no "to" - AND it still doesn't do away with the need to click "load previous entries" TONS of times. It's only loading about 5-10 minutes worth at a time now - its going to take forever to go back 28...

    Question firewall order of rules

    I just started using Plesk firewall, and I looked for documentation on the order of rules but found no mention. Does Plesk Firewall stop evaluating rules after the first match? Or do I need to list all Allow rules first, then all Deny rules? Or....???

    Issue Panic! I changed maximal_queue_lifetime then checked it to find this strange reply

    I changed maximal_queue_lifetime to one day, then checked it. I do have mime_header_checks but I didn't expect to see this - plus the lack of a space there also concerns me. I'm not sure what this will do, if I should be worried, or how to fix it if it really is a problem. ANY suggestions...
