• 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.

Recently I have an interesting problem with the emails that are be sending to Yahoo.com.
All emails that are bigger than 1 Mb are disconnected by yahoo.com

(deferral: Connected_to_98.137.54.237_but_connection_died._(#4.4.2)

Emails are still in queue.

The interesting part is that All emails under 1 Mb even with multiple attach files are delivered successfully.

My main IP is not blacklisted and I using Domain keys too.
I tried with Postfix and Qmail and the problem persist.
I send requesting help from Yahoo, but no answers yet.

Somebody with the same issue ?
