Bug#422719: exim4-config: Please add commented SYSTEM_ALIASES_PIPE_TRANSPORT setting as example

[Olivier Berger]

Package: exim4-config
Version: 4.63-17
Severity: wishlist

Setting aliases in /etc/aliases with pipes won't work until
SYSTEM_ALIASES_PIPE_TRANSPORT is defined, with the system_aliases router
provided.

Error reported will look like == |/usr/lib/sympa/bin/queue sympa
<sympa at yourhost> R=system_aliases defer (-30): pipe_transport unset in
system_aliases router

I suggest to add somewhere in the files shipped in
/etc/exim4/conf.d/main a commented snippet like this :

## Uncomment this to allow the use of pipe aliases in /etc/aliases (see
## router/400_exim4-config_system_aliases

#.ifndef SYSTEM_ALIASES_PIPE_TRANSPORT
#SYSTEM_ALIASES_PIPE_TRANSPORT = address_pipe
#.endif

Hope this help.

Best regards,
