• 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.

QMAIL Relaying

Z

ZopfWare

Regular Pleskian
It seems that all implementations of Qmail on Plesk servers are allowing email to APPARENTLY be relayed if the email address in the RCPT TO: contains an address like spamtest%abuse.net

It correctly rejects relaying (we have SMTP AUTH) if the address is of a standard [email protected], but seems to indicate via a 250 response that it has successfully relayed when the address is someone%somewhere.com

Because of thsi our servers are getting blacklisted as open relays on ordb.org and several other sites.


Does anyone know how to fix this?
