  • 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.

I tailed the maillog and then tried to connect. I am getting smtpd service unavailable. I'm not sure what to do to get it running.

Hi techguyal,

pls. restart the depending service with for example:

Code: 
service psa-pc-remote restart

service postfix restart

service dovecot restart

If you use as well "Premium Outgoing Antispam", pls. don't forget to restart it with for example:
Code: 
/etc/init.d/ctasd_initd start
/etc/init.d/ctmilter_initd start


Pls. check, that no firewall or ( possible ) Fail2Ban - entries block the connections and make sure, that IF you use Fail2Ban, that localhost ( 127.0.0.1/8 ) and each of your server IPs are whitelisted.


If you still experience issues/errors/problems, pls. don't hesitate to use the Plesk Repair Utility with for example:
Code: 
plesk repair mail -y -v
