Alberto Bertogli 905161c537 test: Add a test for Exim interactions
This patch adds a new test which makes chasquid send and receive email to/from
Exim.

To make it work we need to add two testing flags to the SMTP courier, which is
not ideal but doesn't muddle the code much.

The test is not very portable, and assumes an exim binary is available, but
does not have to be installed in the system. It includes a helper script to
fetch one from the Debian archives.

# This test checks that we can send and receive mail to/from exim4.
#
# Setup:
# - chasquid listening on :1025.
# - exim listening on :2025.
# - hosts "srv-chasquid" and "srv-exim" pointing back to localhost.
# - exim configured to accept all email and forward it to
# someone@srv-chasquid.
#
# Test:
# msmtp --> chasquid --> exim --> chasquid --> local delivery
#
# msmtp will auth as user@srv-chasquid to chasquid, and send an email with
# recipient someone@srv-exim.
#
# chasquid will deliver the mail to exim.
#
# exim will deliver the mail back to chasquid (after changing the
# destination to someone@chasquid).
#
# chasquid will receive the email from exim, and deliver it locally.
