Modoboa should allow the use of an external SMTP

[Toniob]

Currently, Modoboa considers that the SMTP server is available on localhost. That’s a good assumption for most of the setups. But with bigger networks, it might not be the case. And if no SMTP server is available, some functions are failing : autoreply for example, and mail notifications too.

It should be allowed to configure an external SMTP for all those cases. I’m thinking about some configuration options in the settings file.

And what about to have a list of domains and select a smtp dedicated.

Postfix can select a transport based on the author of the message.

Another idea :
We could also have a list of SMTP. We try to send a message with the first domain, and if it fail, we try we the second smtp , and so on.

Modoboa should allow to use separate smtp setting for each domain
