No the change was correct, but it exposed the next problem which you
now need to solve.

Well you're sending the mail via SMTP, but the receing and sending
system are the same, so Postfix reports a mail loop.
Whichever jailed Postfix receives port 25 mail for any particular
IP address associated with the system must have a different fully
qualified value of $myhostname then the instances that (properly)
forward SMTP mail to that jail. The sending systems likely also
need to have non-overlapping values of inet_interfaces so that
the receving jail's IP address is not deemed to be local to the
sending jail.
Your multi-jail design is necessarily rather complex, and requires
attention to detail to get right. A simpler design may be a better
idea.
