I think Junio's point is that it's easy to start dereferencing NULL, because later parts of the code assume that "host" is always set, even if only to use it for informational purposes. So those callsites either need to be fixed to handle a NULL host, or perhaps something like this instead (totally untested):

diff --git a/imap-send.c b/imap-send.c
