email altervista bloccata "Mail Delivery System"
Ho impostato Google Gmail (browser web) per ricevere i messaggi in ingresso al mio indirizzo email info@robyrocks.it
Ricevo i messaggi correttamente (anche se con una latenza enorme). IL problema si verificata SALTUARIAMENTE quando rispondo (sempre da info@robyrocks.it) usando Gmail.
Ricevo un messaggio da MAILER-DAEMON@unirelay08.hostedemail.com
che mi dice che non è possibile recapitare il messaggio... rinvio il messaggio 1, 2, 3 volte alla quarta volta circa allora funziona e viene recapitato.
