# 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:
#   smtpc --> chasquid --> exim --> chasquid --> local delivery
#
#   smtpc 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.
