I have user, what import his own gmail account into zimbra mail account.
He can download mails from gmail directly into his own mailbox in Zimbra.
We can say he is, John@gmail.com
On my server, have: John@mydomain.com
Someone send email, to email@example.com
user retrive mail... open it, send reply, select firstname.lastname@example.org account.
And write something, and send it...
On another computer, person who read reply, have in FROM email@example.com :/
It, is possible to put there firstname.lastname@example.org ?
Any idea... i think gmail have avabile remote SMTP server, why not log into john@gmail account and send mail throught his mailbox ?
