'NoneType' object has no attribute 'domain'

Hey,

If I try to delete a mail address (from the child domain “mail.xy.com”, which is automatically created), I get the following error message:
‘NoneType’ object has no attribute 'domain

Therefore I cannot delete any email addresses

Hello,

We also facing the same issue '‘NoneType’ object has no attribute 'domain
while trying to delete any email account . Please provide a solution for this ASAP.
