Hello,
I have the following problems configuring DSPAM with Postfix.
If I forward a "retrain mail" to <spam-user@domain> with
ParseToHeaders on
ChangeModeOnParse on
ChangeUserOnParse full
dspam works as expected, but the sender returned mail doesn't contain
the msgtag.spam footer.
But I would like a single spam|notspam alias mail, so I set
MySQLUIDInSignature on
ParseToHeaders on
ChangeModeOnParse on
ChangeUserOnParse off
In this case the forward email to the single email for all users
<spam-train@domain> is correctly accepted and the message retrained as
I see in user log:
1319191369 M Test Comune
<testcom...@example.com> 13,4ea13b2b119611447418843 Fwd: U're under
arrest Retrained <4ea1434a.5020...@example.com>
(I see above also on web gui)
But the dspam doesn't return the mail to sender, and syslog claims:

dropping message.
If I also add
ChangeUserOnParse full
then dspam send the returned email, but it sends it to strange
inexistent rctp-to chars.
Of course, all work well during dspam checking and delivery of
non-training mails (not starting with spam-|notspam-). Signature added
and delivery from dspam to MTA is successful.
Could you help me?
Thank you very much for every hints.
Here's the postfix master:
