exim4 problems on Hurd

[Svante Signell <svante.signell@telia.com>]

Hi,

when installing exim4-daemon-light the daemon refuses to start:

Setting up exim4-daemon-light (4.72-4) ...
Starting MTA:2011-01-23 11:41:10 Exim configuration error:
  TCP port "smtp" not found
invoke-rc.d: initscript exim4, action "start" failed.

Is this due to Hurd or exim4? Which package provides the smtp port?

Thanks!
