I have found this feature to be useful in the past.
Many ISPs or intranets will authorise connection to an smtp server based
on IP address/hostname instead of username/password, so as to allow open
access but limit it to only those using that ISP or within that
network. For those who have to use such a set-up, but might connect to
the internet from different places, it saves on having to change the
smtp server with each location, albeit a bit slower when connecting
somewhere where the server is lower down in the list, as it has to wait
for the other(s) to fail first.
Nowadays I am lucky enough to have a user-authorised SMTP server that I
can use from anywhere, but I also have my ISP's non-authorised SMTP
which also works next in the list as a back-up.
