However, you can still do what I did with the 1.3.1 fetchmail. Our
local friendly sysadmins already had sshd on the mailserver, so I
compiled a copy of fetchmail in my ~/bin directory on the mailserver.
Then, my /etc/ppp/ip-up script (this was under bo) did:
HOME=~martind su martind <<EOD
cd ~martind
m4 -DIPADDR=$4 < jhunix.fetchmailrc | \
ssh jhunix.hcf.jhu.edu 'umask 077; cat > .fetchmailrc'
./bin/getmailloop &
EOD
Where jhunix.fetchmailrc was a file that looked like this:
poll localhost proto imap
user xxxxxx with password xxxxxxxx is martind here
smtphost IPADDR
And ~/bin/getmailloop is just a script that every fifteen minutes does
ssh jhunix.hcf.jhu.edu bin/fetchmail
Of course, this requires that you set up passwordless logins with ssh
for this to work; not everyone will let you do this.
Now this still has all of your mail travelling over the network
unencrypted; however, your username and password aren't ever sent over
the network (except inside an ssh connection).
