"aren't deliverd" is not much of a problem description. Please provide
the details.

As I understand, this is your setup:

A ("master smarthost")
^
|
B ("smarthost")
^
|
C

So, mail from C "aren't delivered". But which host rejects them? The
hostname in HELO is usually totally irrelevant for relaying, so I doubt
that this is the problem. (N.B., there is no way to provide an IP _and_
a hostname in HELO.)

C is probably not allowed to relay in B's config, so what you need is to
put C's IP (or hostname, if you have proper A and PTR DNS records) in
B's relay_from_hosts hostlist. But without log excerpt (at least from B,
preferably also from C), this is only a wild guess.
