I didn't find the alias that appears on pop-up.
zimbra@mail:> zmprov gaa -v mydomain.es | grep zimbraMailAlias
zimbra@mail:> zmprov gaa -v mydomain.es
We don't have any alias on mydomain.es. And i can't erase this domain because i get this message:
Is not possible erase this domain because isn't empty. First delete all accounts of this domain.
I create with zmprov command some accounts with accents before, few months ago. I used phpLDAPdmin for connect with Zimbra's ldap server and here i see all entries for mydomain.es and i can delete too.
I add bad zimbramailalias including names with accents. From zimbraAdmin web interface get erros but using phpLDAPadmin i can improve them.
Now i can go to Alias tag from zimbraAdmin web interface and erase mydomain.es
