The issue is related to DomainKeys spam protection feature, which is enabled in Plesk, by default. Mail may be deleted by this feature. DomainKeys module verifies mails only if sender is not local and receiver is local.
DNS should be checked on the external server side: system administrator of the external (sender) server has to setup DNS correctly so that they comply with DomainKeys.
If Plesk administrator trusts the sender of the external server and is sure that messages from this server should not be declined, it is required to turn off DomainKeys for incoming messages: Plesk > Tools & Settings > Mail server settings uncheck Verify incoming mail
If this did not help do the following:
Disable (set value to 0)
HKEY_LOCAL_MACHINE\\SOFTWARE\\Mail Enable\\Mail Enable\\Agents\\MTA\\Pickup Event Enabled
Send message again.
