Bug#392993: exim4-config: newly debconfized dc_localdelivery option breaks non-standard setups

[Marc Haber]

Package: exim4-config
Version: 4.63-5
Severity: important
Justification: maintainer's opinion

Hi,

when a local admin has set dc_localdelivery to a custom transport,
dpkg-reconfigure exim4-config will overwrite this with one of the two
standard transports, mail_spool and maildir_home.

This is a clear bug as local configuration is overridden by this
automatism.

The easiest fix will probably be if exim4-config.config omits the
localdelivery question if a non-standard transport was entered
manually. This is, IMO, ok since the local admin has already fiddled
with the configuration.

Greetings
Marc
