What happens when the dialup link dies is the equivalent of any network outage
during a
conversation; the TCP/IP stack and the application have to handle it.
DDNS is a different question altogether; it's what allows external server to
connect to you; it
doesn't bear on your connection to them unless they're performing reverse name
resolution.
If your email is readable at all, it's already been read by the time your ISP
gets it.
What happens between you and your ISP is about as private as you can get,
compared to what the
rest of the Internet.
If your mail is that important, encrypt the mail, not the traffic channel.

Anyway, just inbetween,
there is alway the possibility that my exchange server sends an ETRN and the
dialup link goes offline for some reason - DDNS wouldn't be aware of that
fact. In the meantime, another computer might get my former IP adress and
the remote mail server would try to deliver the queue to that computer. It's
only a little chance that this happens, but it bears some risk. I wouldn't
want my mails to be read by some unknown person.
