I can second this; having deployed a bunch of mailing list servers
myself, I can tell postfix is _very_ efficient. One can tweak it even
further using multiple instances [0], thusly each 'tuneable' to special
purposes (e.g., serving mailing lists).
exim [1] also is very powerful and on some topics even more
configureable, but IMHO not as easily implemented as postfix and, due to
it's design, not as efficient.
