• Our team is looking to connect with folks who use email services provided by Plesk, or a premium service.

  • 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.

    SSL POODLE / SSLv3 bug

    You would be best to configure the file as per the advice in the KB article - some of those settings won't work. In particular you will need to change the following back to the original setting for the service to start: POP3DSSLSTART=YES Without this set as above the service will not start.

    SSL POODLE / SSLv3 bug

    We have been in touch with Parallels via ticket and they have confirmed that the suggested ciphers do not work for Courier IMAP. They say that they will be updating the KB article with the correct ciphers.

    SSL POODLE / SSLv3 bug

    @UFHH01 Thanks - what do you use in your imapd-ssl file for TLS_CIPHER_LIST?

    SSL POODLE / SSLv3 bug

    Unfortunately, that does not fix our issue - we continue to see the following errors in the maillog (and the mail server does not respond on port 143 or 993): Oct 20 15:14:19 nsxxxxxxxx courier-imaps: couriertls: connect: error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher The...

    SSL POODLE / SSLv3 bug

    Thanks for your response and suggestions. We have checked all file paths, permissions and certificates and all are correct. The only way we got this to work with mail clients is to modify the TLS_CIPHER_LIST value in /etc/courier-imap/imapd-ssl to the following (as per Bobcares article at...

    SSL POODLE / SSLv3 bug

    @UFHH01 Thanks for your suggestions. We have reissued the certificate but this had no effect - same errors in the log files as follows: Oct 19 12:56:57 nsXXXXXXX courier-imaps: couriertls: connect: error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher I've tested this on several...

    SSL POODLE / SSLv3 bug

    I have tested with other mail clients (eg Thunderbird 31.2.0, Mail 17.5 on Windows 8) and the problem is the same - mail on port 993 doesn't work after SSLv3 is disabled and the following error is logged in maillog: Oct 19 07:59:49 nsxxxxxxxx courier-imaps: couriertls: connect...

    SSL POODLE / SSLv3 bug

    The mail client is Mail on iOS 7 and also Mail on the Mac (don't know specific version on Mac). Anyone else tried secure POP/IMAP after applying the recommended changes?

    SSL POODLE / SSLv3 bug

    After applying the recommend changes to Courier IMAP/POP files users who access mail via SSL are unable to connect to the server - the following errors occur in the mail client: There may be a problem with the mail server or network. Verify the settings for account or try again. The server...

    Clear SpamAssassin database

    The SpamAssassin bayes database has become ineffective on one of our servers and we want to wipe it and start fresh - can anyone confirm how to do this on Plesk 11.5.30?

    FTPS not working

    After opening a ticket with Parallels on this, they confirmed that FTPS actually works on port 21 (not port 990). You need to set the FTP client to use "Require explicit FTP over TLS" for the encryption mode while still using the standard FTP protocol on port 21. This is not included anywhere...

    FTPS not working

    That's correct - we want to use FTPS without enabling shell access for users, but the server does not seem to be listening on port 990. Is anyone else's Plesk 11.5 server listening on port 990 or is Plesk's implementation of FTPS different from what I am expecting? The documentation for this...

    FTPS not working

    Telnetting to port 990 doesn't work, but port 21 does - is port 990 definitely the port that Plesk runs FTPS on?

    FTPS not working

    This is what we are getting in FileZilla when attempting to connect to ftps://server.hostname:990: Status: Resolving address of server.hostname Status: Connecting to 1.2.3.4:990... Status: Connection attempt failed with "ECONNREFUSED - Connection refused by server". My IP is...

    FTPS not working

    We just upgraded from Plesk 10.4.4 to 11.5.30 and can't seem to get FTPS to work. I presume it should be running on port 990, but the server is not listening on that port (only 21 for FTP). netstat -lptu | egrep 'ftp|990' tcp 0 0 *:ftp *:*...

    Outbound Antispam Replacement

    Is there any alternative available for Plesk 11.5? Having just upgraded from 10.4.4 to 11.5 we are not ready to upgrade to Plesk 12 so are there any other solutions to filtering outgoing mail for spam?

    Can't modify cron, change admin pass or use watchdog

    As far as i'm aware, there has been no fix for this issue as we are running the latest update of 10.4.4. The way we work around this is to run the server_pref command hourly via a cron job - not ideal but has prevented any ongoing customer issues. I haven't tested 11 to confirm if the issue...

    Can't modify cron, change admin pass or use watchdog

    We are seeing this issue in Plesk 10.4.4 Update #36 - we run the command below and the 'No secure shell available' message goes away: /usr/local/psa/bin/server_pref -u -crontab-secure-shell /bin/sh But after some time, the 'No secure shell available' message comes back and the only way to...

    Mail forwarder not working

    It seems that Qmail runs the 'Handlers Filter' on all forwarding email addresses before sending the message, and if any one of those addresses is rejected then this results in the message failing. For example, let's say an email address is set to forward to these addresses: user1@domain.com...
