Hi list,

After a decade, I get to run a mail server again. Back then, I had used
DSPAM. Now, I want to give CRM114 a try. Excuse my newbie question.

I find all the X-CRM114 lines appended to the body of incoming emails.
That cannot be correct, or? Interestingly, it starts working if I remove
the CR from the RFC5322 email:

    $ file /tmp/SomeMail.rfc5322.eml
    /tmp/SomeMail.rfc5322.eml: SMTP mail, ASCII text, with CRLF line
    terminators

    $ wc -l /tmp/SomeMail.rfc5322.eml
    98 /tmp/SomeMail.rfc5322.eml

    $ cat /tmp/SomeMail.rfc5322.eml | ./mailreaver.crm | tail -n 6

    X-CRM114-Status: UNSURE (   0.00  )
    X-CRM114-Notice: Please train this message.

If I convert it to "unix style" line breaks it appends the X-CRM114
lines to the header. As it should be - I think:

    $ cat /tmp/SomeMail.rfc5322.eml|tr -d '\015'|./mailreaver.crm|grep
    "^$" -B4 -A3

The mailreaver.crm is the unaltered one that shipped with Ubuntu 14.04.
Is this behavior normal or am I missing something?
