Do you have the original mail (the 6Kb version) somewhere? In raw

Dear Stevan,
Hello Laurence,
I have finally managed to track down a raw copy of the mail, which I have
attached.
thanks. I have already started to look at the file. I don't get that
6.2Kb size here with the original file but who knows what Exim did to
the original mail to get about 2Kb more in size than the file you have
attached? From the past I know that Exim has (had) issues with 8bit
messages and transformed them into 7bit. Anyway... that original size is
not the problem.
I don't believe there is a way to check the size of the mail when exim
delivers it to dspam, unfortunately
Okay.
Bye for now,
Looking now more closer to the original message you wrote.... I realize
that the message got truncated before the dot. Usually that kind of
stuff happens if the dot is the first character and it is not properly
escaped (dot stuffing. See
http://tools.ietf.org/html/rfc2821#section-4.5.2). But that dot in your
message is at the end of the line. Somehow I can not believe that it is
dot stuffing issue. But who knows? It looks like and it smells like a
dot stuffing issue.
So there are IMHO two possible scenarios (if it is dot stuffing):
1) Exim get's the mail correctly and does not make proper dot stuffing
when sending it to DSPAM (very unlikely since you use pipe delivery and
not SMTP)
2) DSPAM got it properly from Exim and has an issue when sending it back
to Exim
Unfortunately I don't have Exim over here and any test I did, did not
result in a truncation. Can you on your end try to send that mail again
into your Exim MTA and look what is happening? Maybe you have the
possibility to turn on more verbose logging?
Can you try to (keep in mind that the message will show up on the
original date (aka 05.10.2011) in your inbox):
cat /path/to/the/raw/message/you/sent/me | sendmail -oi l...@lwithers.me.uk
Do you still see the message being truncated?
Can you try to look what DSPAM would do with the message?
dspam --user l...@lwithers.me.uk --mode=notrain --process --deliver=stdout
< /path/to/the/raw/message/you/sent/me
Do you see the whole message or do you see a truncation? (I assume no
truncation because it is a delivery to stdout and not to a SMTPD).
Could you post your dspam.conf so that we can see what and how you use
the delivery agent inside DSPAM?
