I have just finished migrating from SBS to 6.0.6 FOSS. And a couple of users are complaining that they cannot see some images using the webmail or desktop client in mails that are sent to them.

Further investigation shows that they are jokes, kittens etc generally with lots of superfluos microsoft markup and barely readable source. All seem to be referenced by CID: and show that something is attached but dont show the attachments

Though if downloaded into another mail reader osx mail, thunderbird or outlook they seem to display fine.

I was just wondering if this is normal and to be expected or if there is a fix or work around I can implement.

Only really found one bit of info that seemed relevant here: https://issues.apache.org/activemq/browse/CAMEL-2054
