This is the kind of problem that's genuinely hard to fix no matter what.

The issue is; your IP comes from the ISP, and in most if not all cases
then, it comes from the ISP's assigned IPv4 blocks; which will be marked as
dynamically allocated... well, because they are, or at least most of them
are.

Then, the problem comes from the fact that picking out multiple single IPs
from a block to be special-cased by services like Trend is a painful
process, and in the end isn't really so interesting for Trend or even for
Teksavvy given that in the end, they remain responsible for what goes on in
their IP block. That is, unless you pay for commercial service, and
possibly unless you pay and register for your own IPv4 block with ARIN.
Bottom line, most ISPs including Teksavvy don't care that people want to
send email -- because they don't know how you setup your server and what
kind of mail you're sending, and don't want to have to deal with spam.

That said, I know Teksavvy provides a SMTP server; and presumably you can
forward your mail through them while retaining your own domain name and
infrastructure for receiving, so I guess you've already worked around these
issues.
