• 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. If your responses match the persona we are looking for, you'll receive a link to schedule a call at your convenience. We look forward to hearing from you!
  • 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.

Resolved Mail Relay permitted only to horde

... but, with a second thought, this shouldn't be necessary as Horde users should be verified... or at least that's what happens with Roundcube... o_O
 
White List: 127.0.0.0/8
My goal was block relay service and permit only Horde smtp messages

Good. I asked as I haven't seen my answer flagged with a "like" nor as the "best answer" like is customary here., but no problem!

Anyway I'm a little bit confused: AFAIK you don't need your IP to be in white list if you authenticate with your SMTP server, and I think Horde should do that user authentication, as Roundcube does.

In my server I have that white-list as it is needed by other software (the "mailman" mailing lists manager), but I think there are consequences to that like e.g. opening to every script the possibility to send mail in an authenticated way.
 
Ok, the problem is not authentication. I don't want open authenticate realy because some users get spam malaware. So I only need to send mail with horde webmail. White list works well. Thank you
 
Well, problem is not solved.
white listing is not the solution.
My goal si permitting mail sending only from horde and no other way.
