  • 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 How to Block SMTP AUTH attempts using a RBL

    No, doesn’t work for my needs, my problem is not spammers, it’s a hacker. Post screen is nice working for 25 port, and spam, but not for before SMTP AUTH, that’s my problem, in SMTP AUTH attempts.

    Resolved How to Block SMTP AUTH attempts using a RBL

    Yes, I have already months ago: 1.- To 15,000 IPs 2.- SMTP_AUTH = 1 I have a really good RBL that I checked a lot of times vs attacker IP's and my client IP's and it's 99% exact with the attacker IP's, so, yes a RBL will work if there's a way to block the SMTP AUTH using it.

    Resolved How to Block SMTP AUTH attempts using a RBL

    Yep, I have them to 1 months ago, we don't have many clients, so in any false/positive is best for us to block all the wrong tries. But like I wrote, the have a LOT of IP's, it's a directed attack as they know the usernames, so is not kind of a "wide" attack, if we had the possibility to use...

    Resolved How to Block SMTP AUTH attempts using a RBL

    Could be good idea, can you tell me how to disable SMTP AUTH on 25? Hmm it's spam? does this does what I'm looking for? I´m happy with Juggernauth, just lacking of this protection that could be useful.

    Resolved How to Block SMTP AUTH attempts using a RBL

    Thanks Peter, Yeah, would be great to accomplish this, I tried using Postfix main.cf, with these options added: smtpd_client_restrictions = permit_mynetworks, reject_rbl_client XXXX.XXX (RBL list) smtpd_delay_reject = no But at the end, it blocked all the attempts, not based on RBL

    Resolved How to Block SMTP AUTH attempts using a RBL

    Hello, I'm getting a lot of SMTP AUTH intents, I have installed CSF, Juggernauth security plug and well all the intents become banned, but the "hacker" is trying every minute using a lot of different IP's I know, it's quite common, but I want to block them, I have a very good RBL, I have...

    Resolved How to ignore POP3/IMAP login attempts for a non existent domain in my server?

    Hi again Peter, now they are trying with different usernames, but common ones, for example test@.. admin@.. we don't have any of these email addresses, it's possible to block instead the domain, the user "string"? I already tried changing the domain to the user strings, but they still can try...

    Hi all, I have a kind of annoying problem, in the past, my main server IP belong to a very known domain website, they move their website/email server to a new IP range and I got their IP assigned (didn't know about this when I received them).
