Hello, I have created two very simple shepherd services for two
different mail programs (offlineimap and davmail). Both of the programs
are able to run without problem when ran from the commandline, but both
of them fail with networking related errors when I try to run them as
shepherd services.
I have read all the relevant sections of the manual and looked at
similar shepherd services in the source code, but I can't find anything
that I am missing in my services. I am either missing something obvious
here or shepherd is doing something weird that messes up these programs.
Here is my service definition for offlineimap:

They both seem to fail when opening an *outgoing* socket, but davmail
seems to be able to start *listening* on several ports just fine.
