This is probably the case. However be aware that some RBL's will not
accept removal/re-test requests for dynamic IP ranges given out by
ISP's.

Yes, your messages are being flagged because you're listed in those
RBL's:
X-Spam-Status: No, hits=0.6 tagged_above=-999.0 required=3.0 tests=AWL,
BAYES_00, L_RCVD_IN_RBL_2, RCVD_IN_DSBL, RCVD_IN_NJABL,
RCVD_IN_NJABL_PROXY, RCVD_IN_SORBS, RCVD_IN_SORBS_SOCKS
X-Spam-Level:
Luckily your message gets negatively scored by bayes, sites running
network checks without bayes will tag your messages as spam, and if you
incorporate any 'spammy' tokens into your mail it may get tagged
regardless of bayes at some sites.

Some would say, and I'd agree, that you should not be running a mail
server on a dynamic IP range because of this exact reason, and you'll
have other problems - some sites refuse mail from dynamic IP ranges with
the view that you should be relaying through your ISP.
In addition, your ISP is encouraging such abuse by *not* blocking port
25 inbound, my ISP does this as a matter of course (you can ask for it
to be unblocked - in which case they routinely test for the existence of
an open relay).
Get a static IP and your problems will [mostly] magically disappear.
In the short term your best bet is to get a new [dynamic] IP.
