[Dspam-user] DSPAM modifies mime layout

RW

I've noticed that DSPAM can slightly modify the mime layout when mail
is piped through it with --stdout. It's a problem if the output is
piped through another filter, such as SpamAssassin, because it
changes the DKIM body hash.

In the example below two extra blank lines are inserted, one after each
of the two closing boundaries.



MIME-Version: 1.0
Content-Type: multipart/related; boundary=001a113eb6969361b80530203ac8

--001a113eb6969361b80530203ac8
Content-Type: multipart/alternative;
boundary=001a113eb6969361b20530203ac7

--001a113eb6969361b20530203ac7
Content-Type: text/plain; charset=ISO-8859-1;


--001a113eb6969361b20530203ac7
Content-Type: text/html; charset=ISO-8859-1

--001a113eb6969361b20530203ac7--
--001a113eb6969361b80530203ac8
Content-Type: text/plain; charset=ISO-8859-1;


--001a113eb6969361b80530203ac8--

That should, of course, have been one line.

Hi,

Are you placing the DSPAM signature in the body or just the headers? If
you are putting it in the body, try not doing that.

Regards,
Ken
