Hello,

I am not 100% sure what the best/correct dependencies for Debian's
systemd unit (Type=exec) are.

For reference exim git has:
Requires=network.target
After=networking.target

while Fedora, Gentoo, Opensuse use
After=network.target

and we (Debian) currently have
After=network-online.target
Wants=network-online.target

* I think exim.git's "After=networking.target" is a typo and should
  read "After=network.target"
* Reading https://systemd.io/NETWORK_ONLINE/ network.target is very weak
  and "its primary purpose is for ordering things properly at shutdown",
  so Requires/Wants should not make a significant difference.
* The same page says "for example network server software should
  generally not pull this [network-online.target] in." So Debian might
  have made an error and should switch to network.target. Except exim is
  not just a server for incoming connection but also makes outgoing
  connections.
* exim usually will not be able to do something useful without
  nss-lookup.target and nss-user-lookup.target so these are candidates
  for After-directives. What about remote-fs.target or using 
  RequiresMountsFor=/home or RequiresMountsFor=/var/mail?
