sendmail 8.10.1 can use sasl to do authentication - the debian package
works with netscape, but some levels of ie and outlook require LOGIN
support, which isn't supported in the current debian libsasl code.
sendmail 8.11.0Beta1 also supports TLS (SSL/SSH type encryption), but
there are problems creating a debian package in the US - need new
debian policy.

Welcome to the semi-bleeding edge

sendmail 8.10.1, postfix-tls and file a bug requesting fetchmail to be
compiled w/sasl or tls (it supports one, I forget which) - again this
doesn't really fit in with current policy - encryption support ;-{
At this point in time, I'd recommend against AUTH after POP, there are
better alternatives
