• 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.

Hi,

Some of my customers are sending me their return email errors so I can see whats the problem, now some of the mailer daemon says>
<[email protected]>:
Sorry, I couldn't find any host named tnc.org.gt. (#5.1.2)

<[email protected]>:
Sorry, I couldn't find any host named fcg.org.gt. (#5.1.2)

<[email protected])>:
Sorry, I couldn't find any host named defensores.org.gt). (#5.1.2)

<[email protected]>:
200.12.63.41 failed after I sent the message.
Remote host said: 552 5.6.0 Headers too large (5128 max

The domain name is not pingable, it does not respond BUT the domain name is registered and exists, they must have some kind of firewall.

My question is> the qmail can send email to a non pingable domains????? because I have get to many errors, to many of this mailer daemons telling me that the domain name couldn't be found when the domain exists and is running.

Any ideas????
