So I recently did a bunch of upgrades when I discovered that my DSPAM
integration needed some realignment.
I currently have the following
new spam-scanners setting in my amavisd.conf
@spam_scanners = (
['DSPAM', 'Amavis::SpamControl::ExtProg', $dspam,
[ qw(--stdout --process --deliver=innocent,spam --mode=tum
--tokenizer=chained,noise --user), $daemon_user ],
learn_ham => [ qw(--class=innocent --source=error --user), $daemon_user ],
learn_spam => [ qw(--class=spam --source=error --user), $daemon_user ],
mail_body_size_limit => 64000, score_factor => 0.1,
],
['SpamAssassin', 'Amavis::SpamControl::SpamAssassin' ]
);
Which is getting me the following log entries

Aborting.

dropping message.
I *suspect* that the extraneous '\rs' are confusing amavis string
recognition for 'ham vs spam' 'spam vs innocent'; and then also causing
the signature to be unrecognised.
If I manually enter a dspam command-line with source=error something
like this
dspam --stdout --debug --user vscan --source=error
--signature=5899e56780281410093335 --class=innocent
It all seems to work... I also notice that other mailing-list users also
have the extra '/r's in the postings
https://groups.google.com/forum/#!searchin/mailing.unix.amavis-user/dspam%7Csort:relevance/mailing.unix.amavis-user/tFKiT3HzqNQ/FNxpWTCQ7XUJ
Also I notice that the spam_scanners has zero means of instructing the
learn_ham or lean_spam what the signature is. Is there a syntax I can
use to wrapper --signature=X-DSPAM-Signature to make it meaningful ?
thanks
Barry
