  • Applies to:
  • Plesk 11.5 for Windows


Here are steps to reproduce the issue:

  • Create a customer with IDN name in email, e.g. “email@просто-сайт.рф
  • Create a subscription for this customer, “просто-сайт.рф
  • Backup the subscription
  • Check backup results:

    Warning:        domain "просто-сайт.рф"
    Cannot dump dns zone with id '12'[Email value 'email@просто-сайт.рф' is not valid]


Such behavior is considered to be a software issue. The fix will be included in future Parallels Plesk Panel updates released after 11.5. You can track it using the following ID:

PPPM-536 - Cannot dump dns zone while creating a backup if e-mail contains Russian international symbols

Temporary workaround

Change customers email with non-russian domain name (with customer's confirmation only):

Home > Customers > %customer% > Edit Contact Info

Search Words

IDN domain name

Russian symbols

cannot backup a domain

invalid customer's email

invalid DNS zone
