Something's wrong. It should say alpha5.
You are true, I messed up. Sorry.
This turned out to be more complicated than I initially expected.  Why?
Well,  FWIW ...
I've a spec file that I use to build an RPM for Centos5.2-64 which
combines the dovecot-alphaX with the corresponding sieve and managesieve
sources.  So building a nightly with this does not work because the
managesieve is not in sync (unless you can point me to a nightly of that
as well) and won't build with the existing managesieve-alpha5.
I ended up dropping back to building an RPM of just the dovecot sans the
sieve portion using the nightly tar file.  Having no sieve of course
means that I had to delete that stuff from the dovecot.conf.
Here is what I now get with the install of just the dovecot nightly (no
sieve):

Interesting: I notice that the "listen" does not show up in the last case.
