[Pkg-dspam-misc] Bug#644392: dspam truncates mail

[Laurence Withers]

Package: dspam
Version: 3.10.1+dfs
Severity: critical
Justification: causes serious data loss


I have discovered that dspam is truncating inbound email after it has been
scanned. Please consider the size field (S=) in the following exim log
entries:

As you can see, there is a significant drop in size between the mail being
received from a remote SMTP server (6021 bytes) and after it has been scanned
by DSPAM (3591 bytes).

The mail as it should be is visible here:

The mail as I received it ends after the word "earlier" and immediately
before the period. I can of course provide a copy as written in my .maildir
on request.
