If your mail is handled through an IMAP server (rather than POP), then
this wouldn't be the case.  Your mails are stored on the server, and
your mail program browses them.  If you want to test a mail client, or
have to put up with continually replacing your OS installation, it's the
best way to go about it.

As for the rest of your work, there are various ways of dealing with
that.  There's the backup and restore technique.  Or, keep /home as a
separate partition, so that you can re-install around it (still make a
backup though, just hope you're lucky enough to not have to make use of
it).  Or you can keep your files in a separate server, which could be
another computer, or just a networked drive.

These days, it's next to impossible to get by with just one computer.
You almost need another one so you can research, on-line, how to fix up
the other one when it goes doolally.  If you're in that position, you
may as well install a long-lived distro on one, and use it as your
server.

All mail to my mailbox is automatically deleted, there is no point trying
to privately email me, I will only read messages posted to the public lists.

George Orwell's '1984' was supposed to be a warning against tyranny, not
a set of instructions for supposedly democratic governments.
