My current ISP (Verizon) wants US$100/month more for a static IP address
than for a dynamic one. In addition, I am not permitted to use my own
MTA (in my case, sendmail) unless I have a commercial account instead of
a home owner's account.

My sister lives in France. I believe her ISP is the French Post Office.
While I can receive e-mail from her, she cannot receive e-mail from me,
even though I use Verizon as my ISP. My home has a dynamic IP address,
but I assume Verizon have static IP addresses. We have worked on this
for several years, but I cannot send to that sister.
I have another sister in Canada. She has no trouble sending e-mail to
her sister in France.
Someone in France does seem to be blocking Verizon. At least, they are
blocking me, and I cannot imagine it is just me.

Maybe France is blocking all of USA, or all of Verizon.
