Of course, if they do start enforcing this, then people who own smaller
domains are in a catch-22.  They can't run their own MTA -- even if they have
a static IP, often it winds up in one of the dynamic-IP blocklists, which
means a lot of sites will reject their mail.  When they complain, the
suggested solution is always to go through their ISP's smarthost, but if that
avenue is blocked off as you suggest, what's left?  We'd be back to the days
when small businesses were stuck having "@aol.com" addresses.

You have lots of options left:

o  If you have a business account with them especially, ask them
   to remove you from their dialup IP pool, and assign you an
   an address in their dedicated-server pool--My understanding of
   the dialup blocklists is that they often allow the owner of
   the IP range to say which addresses are customer dialups and
   which are dedicated servers.

o  Ask them to set up their mail servers to allow only you to
   send mail from your domains.  (I guess we're assuming they
   aren't competent enough to do this.)

o  Buy fairly cheap remote shared-but-dedicated-server
   (user-mode-linux is popular) type access somewhere, and
   install your mail server on that.

o  Talk with companies who provide mail forwarding services.
   I'm guessing they can also provide trustworthy outgoing mail
   service as well.  :-)
