[CentOS] Story of an email

I'm running postfix + dovecot on my CentOS server,
together with amavisd, clamd and spamassassin,
following the instructions in
As far as I can see it is all working,
but I must admit I'm not clear exactly what path
an incoming email travels along.
I asked this question before, and someone suggested
a document I should read,
but unfortunately I've mislaid the note I made at the time.

So if someone could enlighten me -
or point to a source of enlightenment -
I should be most grateful.
