When email is coming fast from an account I start tracking the number

probably spam.
I also have restrictions on valid domains the from has to match, I
look for URIBLs, high SA scores, etc.
Just curious what others do to detect outgoing spam.
I use Exim for the MTA because it has the power to do the tricks I
need done.
Exim + MailScanner does the job fine here. Just configure MailScanner to
scan outgoing e-mail as well using SpamAssassin and discard anything
over a certain point (I usually say 7.0 as that seems to be the point
where any FPs end).
