Deferred mail with UTF-8 character in mail address


Mar 21, 2019
Mail that include utf-8 character in addresses ends up as deferred.
Any ideas how to solve this ?

hm - seems this is a different issue - please open a bug at (and refer to this thread)

Do I see this correctly - the mail with the non-ascii characters is one of the internal mailboxes?

Thanks! - I responded there and would suggest that we continue on bugzilla
