I'm italian, and your native language?
Now I'll use real domain (not real email adress, just for secutiry reason, I'll take from my fantasy) so I hope it's more easy to understand.
the email are:
1.
school@istruzione.it governative domain
2.
office@scuola.it this is our web-site and mail domain (not the real one this is take from my fantasy)
we have installed zentyal in a microserver with firewall and mail server (this is the fourth zentyal I installed in a school but the first with mail server), created virtual domain (istruzione.it - scuola.it), created one user, from the user panel we set parameter to retrieve mail from external pop3 for
school@istruzione.it and
office@scuola.it. Everything goes well, but wen we try to write to
teacher@istruzione.it from
school@istruzione.it our mail was rejected because the external server refuse to receive mail from itself send by an external (for him) IP. The same for the other mail domain. So I set in zentyal the smarthost to use the istruzione.it smtp server and now domain istruzione.it work fine but not the other, setting scuola.it as smarthost the email for this domain work well but not email with istruzione.it as domain. So how can I set multi relay host to use with different email sender?
If I use a client like thundirbird I can set more email address to retrieve and send each one of them and for each one I can set different smtp and pop3/imap server. What we want is to retrieve all email in our server and work on it using zentyal webmail service, we don't want any client.
Thanks again
