This isn't really firewalls-related, so follow-ups should probably be
off-list...
The main advantage is that an ISP's server is generally well-connected and
highly available. It's also generally on the same subnet as the mail
server where you get your mail. Generally, in the past, large shell
servers have been Solaris boxen, though most ISPs don't offer C compiler
access anymore, it used to be handy for cross-platform testing. Shell
servers tend to be administered by people who're paid to keep them up to
date and secure- for some providers that success rate is high, for others
it isn't. For some things, if they don't run an ident daemon,
they can offer a little more semblance of anonymity. Finally, shell
servers don't tend to be blackholed from an SMTP perspective, while Linux
boxes may fall under the DUL or some other "no customer direct relay"
provision.
In the eggs-and-baskets case, having both available is the best-case
scenerio.
