@zimny I have some doubts, about e-mail module, this is my scenery:
So, firts of all, I would like know if, when I configure the nethserver module, my nethserver connect by pop protocol to the external server, and download all the messages of each mailbox to nethsever, and then how I can configure every mailbox to deliver the messages in to the lan pc’s, and how it deliver, like user1@xxxx.com or user1@xxxx.local, my hosting provider some times is down, and I would like that when that happen all the pc’s, can continue comunicating by e-mail, so when user1 send a email to user2 that e-mail deliver without send to external server, and if the destinatary is another user like xxxx@gmail.com, then wait until the external server is ready, it’s possible to do this?
Do I need work under a domain controller or I can continue just with a workgroup?
