Hello,
I am by no means an expert. It seems to me though that your issue is that you
want that transport to take effect the first postfix instance (in your diagram
the one listening to port 25). Based on the log it seems that the message goes
from postfix to dspam to postfix which then gives it to dspam-retrain. So a new
signature is added before retrain sees the message. Not sure how to fix that
however you want the first postfix instance to follow the transport before
passing to dspam so that it passes to the dspam-retrain script instead which
will then retrain and discard.
Just my thoughts. Also I maintain the rpms for fedora and centos so if there is
a bug let me know.
