Bug#930519: missing versioned dependencies

[Marc Haber]

Package: exim4
Version: 4.92-8
Severity: normal

Hi,

for some possibly historical reason, the dependencies between the exim
packages are not versioned. This might lead to the latest security
updates not being installed if some people just do apt install exim4
instead of the recommended apt upgrade.

I think that our packages should more closly depend on each other to
avoid running an older exim4-daemon with a later exim4-base, forcing
daemon upgrades even if somebody only upgrades exim4.

Greetings
Marc
