"host" in my case is a package that contains:

/usr/bin/host
/usr/bin/mx
/usr/bin/zone
/usr/bin/aaaa
/usr/bin/txt
/usr/bin/ns
/usr/bin/soa

and replaces the bind9-host package.

It just means I can do less typing than when using dig.

I have no idea.

Let's get back to the actual error message you received:

You can either turn off sender verification or use an address that can be
verified.

If it's for cron jobs do what I do and use rewriting in Exim's config to
make them appear from a standard user.

Actually all our servers have a newsgroup on a news server and the root
alias is a pointer to some mail to news software that stores them in an
INN server. Instant archives and searchable to any staff with a
newsreader.
