You're stilling going to lose contents. If dspam fails, the mail is dumped, the LDA returns exit code 75, and the MTA will probably issue a bounce Email to the sender.
which would be OK, if "never loose email contents" means "no message is discarded silently".
no, it is not OK to backscatter because the spamfilter fails
realize that 99% auf junk is using forged senders
recently i got each day some hundret such bounces from mailservers configured by fools reply to spam with forged senders and if i could i would have gone out for beat every responsible admin straight in the face
I may discard emails based on RBLs, but I don't want to discard emails based on statistical fllters, I prefer deliver them in the Junk folder and let the user have a chance to reclassify using dovecot_antispam. And yes, bounce spams to (forged or not) sender is useless
you *must not* discard mails - in no context - period
that's why milters exist to tag between let say 5.0 and 8.0 spam points and REJECT pre-queue based on SpamAssassin and/or ClamAV
maybe dspam can't do that, but it's *abandonware* anyways http://comments.gmane.org/gmane.mail.spam.dspam.user/19136
