• 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.

Plesk 12 smtp differences? (Firewall)

K

kpmedia

New Pleskian
SMTP (submission port) server
SMTP (mail sending) server

- Does one accept the mail on port 25?
- While the other only controls/allows smtp logins?

If so, which is which?

If not correct, then what are the differences?
