Bug#512206: exim4: Starting MTA without network conection (waiting a longer time in boot)

[Renato S. Yamane]

Package: exim4
Version: 4.69-9
Severity: minor

If you power-on your laptop with *no* network conection, you need wait ~40sec in this boot step:
Starting MTA:

IMHO, I think that this service can be loaded in background.

Step to reproduce:
- Power-on your machine with NO ethernet cable and with Wireless card disabled.

Best regards,
Renato
