Invalid jDKIM signature on quoted-printable mails
Hello,
I'm configuring James-3.0.0-beta5-SNAPSHOT to enable DKIM signing. it creates valid signature for plain text mails, but not for quoted-printable mails that made by Apple Mail. I also tried set forceCRLF=false to DKIMSign mailet but no effect. I'm investing this problem and suspecting logics in CRLFOutputStream or RemoteDelivery now but still the cause is unknown.
Is anyone has any hints or ideas to solve this problem?
Also I posted about details of my setup to my blog: http://www.nailedtothex.org/roller/kyle/entry/configuring-james-to-sign-dkim
Thanks.

Hi Eric,
The cause is RemoteDelivery. it crushes validity of the sign through converting quoted-printable to 8bit plain text after DKIMSign mailet has made the sign, due to the property mail.smtp.allow8bitmime=true.
I'm not sure why that property is set true but I guess XML definition will win due to following invocation of props.putAll(defprops).
Sorry come to think of it, I'm not sure where that doc is appropriate. if the jDKIM site has some setup instruction or something, it would be good to place that note.

Re: Invalid jDKIM signature on quoted-printable mails

You are talking about RemoteDelivery and DKIMSign mailet. Which one is
the cause of issue?
The code of RemoteDelivery mailet (line 732) is
// By setting this property to true the transport is allowed to
// send 8 bit data to the server (if it supports the 8bitmime
// extension).
// 2006/03/01 reverted to false because of a javamail bug
converting to
// 8bit
// messages created by an inputstream.
props.setProperty("mail.smtp.allow8bitmime", "true");
The comment is not in line with the code (supposed to be false since
2006, but set to true).
Where would you like to see that doc (in jdkim site, in server site, in
javadoc...?)

I think we always should set this if we use DKIMSign mailet. adding some note to the documentation is reasonable.

Should we always set this property, or is it only valid in your specific
case?
