Bug#917656: libnet-server-mail-perl: FTBFS (failing tests)

[Santiago Vila]

Hello.

According to my build logs, libnet-server-mail-perl (the
affected package against which I initially reported this)
seems to be buildable without errors (not even random) at least since buster.

In normal circumstances I would just go ahead and close the
bug, but due to the multiple reassigns I'm not confident enough,
so I leave it to you.

Thanks.
