was the instance on the mailserver able to write files locally?

What version did you start with? v4.2.3 and v4.2.4 differ only in a
bugfix in the unixsock plugin - the network plugin hasn't been changed
at all.

Does `main' receive values from ``external'' servers?

Why does `main' send the values to itself (the `Server' statement)? And
why do `mail' and `stuff' listen on the interface? Are they supposed to
receive data?

Did you try a tcpdump on `main' to see if data is seen on the interface?
Do you see the data leaving the virtual servers?
