Email in transit between servers can be read by anyone with low-level
access to the network between them. That makes it *possible* to read some
email, but targeting a particular user's email is non-trivial. If everyone
in the group is using, e.g., GMail, this isn't an issue.

Google, at least, doesn't give away your emails or email address. They look
for keywords and display the ads themselves.

Unless messages are encrypted with something like PGP or the entire group

And, again, the hard nut to crack with security is the end users. The
technology may be awesome, but if the users don't use it correctly, it's
easily defeated: bad passwords, shared passwords, public open wireless
networks, naive users, unpatched systems, unlocked screens, etc., can all
undo the best security.
