Initial impressions:

I would rename 's' to 'fd'.  Everyone knows what 'fd' does, s could be anything,
and being an int, it's totally un-typesafe.

I'm kind of tempted to suggest using the prot.c prot_write, prot_read functions
rather than raw fwrite and friends, but it's a real nit - they look fine.  THOUGH,
I would test for errno if you're going to use them.  Running in a real process,
you could signals.  The prot stuff hides that for you.

I guess the nice thing is, it will just fail back to the MTA which will try again later,
so no real damage gets done.

I've got a sneaking feeling that your entire spamtest_parse_hosts could be
turned into a tight little piece of code based on strarray_split() - but it looks fine.

All the code looks like it works (which is not a surprise, because it's been used).
My main concerns would be around signal safety in the file IO syscalls.

Thanks so much for posting it :)  I'll get Ellie to have a look at it (yay minions)
and integrate it.

Cheers,

Bron.
