Postfix

So I installed mutt, and the package depends on postfix, which asks to
be configured through debconf when being installed. I chose the default
"Internet Site" configuration option, and left the "mail name" as the
hostname of my machine, as I'll be overriding the from address in my
mail client anyway so this hopefully doesn't matter.

It seems to work, both through Evolution and Mutt. In my .muttrc I put:

set from=me at mydomain.com
set use_from=yes

and that seemed to set the From header correctly, overriding the
nonsense that postfix would otherwise generate
(mylocalusername at mylocalhost).

So is Ubuntu's 'default' postfix setup like this safe to use? What will
happen in cases of dodgy network connections, like for example I compose
mails offline, or the connection goes down while I'm sending emails, or
I'm on some wireless network with crazy settings. Will I be told if the
mail does not get sent properly? Will mails be held by postfix and sent
later? I tried unplugging my network cable, and mutt just seemed to hang
on "Sending..." until I plugged it back in. When mutt says "Mail sent"
can I safely assume the mail has actually been sent, or could it
actually be hanging around somewhere in the postfix process on my
machine?
