Oh yes, that's what I had in the back of my mind when I asked the question.
So back to enable it again.

Just for the record, I used to do this after every Fedora installation:

yum install postfix

yum remove sendmail

chkconfig postfix on

service postfix start

(well, I still do this -- just did for F17 -- but now 'chkconfig' and 'service' should be replaced by their systemd counterparts)

Works like a charm, as jdow posted, postfix is configured to replace sendmail completely.
