I having a very strange problem here. I will give my situation here:
firstname.lastname@example.org send an inline images email to email@example.com.
So firstname.lastname@example.org preview the email. No problem. Images displayed perfectly.
So email@example.com wish to forward this email to firstname.lastname@example.org. So the email@example.com right-clicked on the mail and choosed "Forward" and enter firstname.lastname@example.org then click send.
Now here is the problem. email@example.com received corrupted image when I tried for first time. But after few time tested, just by doing the same things without changing any settings or preferences, firstname.lastname@example.org able to see the image properly.
After I examined, when user3 are able to see the image properly is when the images in the inline was attached in the attachments list (automatically and randomly); user3 are unable to see the image when the image in the inline was NOT attached in the attachments list.
Why the system will be inconsistency? I also received complain from user that the signature will changing itself (system) alternatively. User only had one signature, let's call it signature A, saved in the preference and set it to default signature. After few days, user wish to change the format of the signature and save it by replacing the old one, so let's call the new signature as signature B. So now the problem occurred that the signature changing itself alternatively to A and B itself.
Anyone facing this problems?? What is the factor you guys suspected?
