Bug#605678: exim4-config: Add another local mail option that forwards everything to external email address

[Ole Laursen]

Package: exim4-config
Version: 4.72-2
Severity: wishlist

Hi!

This is a wishlist - I think it might be convenient if the debconf had 
an extra local mail option where it doesn't try to send mail to external 
adresses, except for local mail which is delivered it to some address 
specified by the user.

I have two use cases:

1. I got exim installed on my laptop but I don't want it to actually do 
anything else than collecting local mail. I use mail apps that talk 
directly to other smarthosts (e.g. gmail or my ISP). However, some 
daemons on the laptop, like cron and smartmontool, sometimes send me 
mail when there's a problem. I'd like to get that mail rather than 
letting it rot in a local mailbox that I never check.

2. I run a web-based company with some servers. One of them runs a mail 
server with internet delivery. The others I don't want to ever try to 
send mail, to simplify management and because some of them are test 
servers where I don't want the possibility of some mail accidentally 
escaping from a test run on a script that works with real data. However, 
I'd still like to get local mail from cron and smartmontools.


So exim should only listen on the loopback interface, external adresses 
get rejected, and any local mail is simply forwarded to some external 
address I specify. Is this feasible? Maybe it's already possible right 
now?

Ole
