Symptoms
It is impossible to see mailing lists created by Plesk in SmarterMail GUI for domain administrators.
Cause
It is default SmarterMail behavior which does not show mailing lists for domain administrators. Plesk does not configure this option somehow as it uses default domain configuration in SmarterMail.
Resolution
To see mail lists via SmarterMail it is necessary to go to SmarterMail, Domain/Edit domain action, Features and toggle Mailing lists checkbox.
