• 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.

    Trends & Patterns in E-mail Attacks

    In the proces of writing a daemon to monitor and respond to failed login attempts, I noticed this pattern repeated numerous times every day: Five simultaneous connections - never any more, never any less: Sep 9 04:00:34 www postfix/smtpd[444]: connect from 592329.soborka.net[94.158.158.194]...

    Disabiling e-mail Forwarding

    FYI: I discovered that the last condition (i.e., "AND mail.redirect = true ;") didn't do anything for paring down the results so I modified the search term by enclosing the word true in quotes and got very different results: mysql> SELECT mail.mail_name FROM mail WHERE mail.redirect = 'true'...

    Disabiling e-mail Forwarding

    Like most hosters - I'm sure - many of our clients create e-mail accounts that forward incoming e-mail to mailboxes hosted on other e-mail services. e.g., Gmail. Lately, though, a handful of these accounts have been receiving a lot of spam (i.e., UCE) and that's been causing a lot of damage...

    FTPS not working

    Failed Mail Authentication

    I guess that what I'm driving at here is: How can I detect brute force attacks against Postfix and stop the ongoing attacks? If I understood how the messages are logged, I might be able to write a simple script that adds a rule to iptables to stop the attacks.

    Failed Mail Authentication

    Lately I've been spending a lot of time grok'ing the Postfix logfile (i.e., /usr/local/psa/var/log/maillog) and I've been noticing a lot of authentication failures (and even one successful break-in). Most entries are just a simple pair of log entries that includes the source IP address and...
