• The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Port forward 587 to 25 - not working

Port forward 587 to 25 - not possible?

I have a customer that has all traffic on port 25 blocked through the ISP. Nothing I can do about it. I want to forward port 587 to 25 on my server's end. I went through and added a rule to the firewall on input, with source port 587 and destination 25. Doesnt seem to work at all. Something I am doing wrong? To the mail services, it wouldnt appear different, just need them to work outside of the restriction from their ISP.

Thanks in advance!
 
Why not just enable the submission port 587 on your server in addition to 25?
 
Yes I see all that wonderful option and just got it working! Thanks a ton!
