This simply doesn't work with your setup, since you want to map a
single Turba attribute (emails) into multiple LDAP attributes of the
same name (mail). This is not supported by Turba.
As you noticed, it works when reading from LDAP, because we combine
attributes value with a customizable separator (defaults to ", ") if
the LDAP server returns multiple values for the same attribute name.
But the opposite direction is not as easy. We don't know if an
attribute value from Turba that contains a separator is really a
multi-value attribute or just contains it by coincidence. We don't
know if the matching LDAP attribute supports multiple values either.
With the flexible approach and attribute mapping that Turba supports,
I don't see a solution for that problem that would work generically.
