I think there might be some miscommunications or misunderstanding here.

Current setup

Customer (dynamic IP from their ISP) -> Customer Exim/Mail Server (in
data center with static IP) -> Intended mail recipient server (using
Barracuda)

Barracuda is rejecting the emails based on the Customer IP, not the
mail server IP. The bounced mail includes a link to Barracuda's site
with that dynamic IP embedded in the link.

Using mxtoolbox's blacklist check, the Server IP is not blacklisted
anywhere not even Barracuda. So it's certain that Barracuda is
blocking based on the sender's ADSL IP.

So if I thought the smarthost suggestion means this

Customer (dynamic IP) -> smarthost (static IP hides customer's IP) ->
Exim (in datacenter, now see only the smarthost IP) -> intended mail
recipient server.
