If you see this IP when you connect to your postfix from the internet,
complain to your new ISP immediately. Connections from outside should
not be NATted.

once again, when you connect from outside to 213.14.BBB.59, do you see
the connection coming from 172.27.203.20?

Sorry I missed your questions.
not misread, you have answered them properly.
Yes I saw connections coming
from 172.27.203.20 and it was me.
it was you in what way? were you connecting from inside IP (192.168.*) to
your public IP (213.14.BBB.59) and saw the connection coming from
172.27.203.20?
That one is called NAT loobback and is required in such case.
In this case, 172.27.203.20 only means that the real source is in your
internal network.
The real problem happens, when you connect from the internet IP and will see
172.27.203.20 there.
Which IP you see connecting on your mail server, when you connect from the
internet?
