Tieni presente che
destination@destinationdomain.it
ha come username
destination
Il problema si presentava su una sola mailbox ( magazzino ) e adesso anche su un'altra ( ricambi ).
Il server e' up2date.
Onestamente non capisco.
Script personalizzati non ne ho fatti, e' una installazione pulita senza modifiche.
Grazie.
