My custom mailbox won't show headers in Outlook

[Thomas Söhngen <th...@tgconsulting.de>]

Hi James Community,

I am working on a mailbox that connects to a custom store. That store 
has its own format to save email messages, so I can't just store the 
byte arrays there and had to write a parser to convert messages from and 
to the custom format of the store. The messages are parsed from and to 
Thunderbird without problems, but I have problems displaying the header 
information in Outlook. This is true even for mails that I saved to the 
mailbox via Outlook, and even if I take the exact header sent to James 
as a byte array, encode it as a Base64 string, save it to the store and 
decode it back directly to a byte array input stream when the message is 
retrieved (so never converting it to a String, avoiding charset issues), 
the header will still not be displayed in Outlook.
Outlook seems to interpret the header in some way, because it finds the 
boundary and the mail body starts at the right position, but it doesn't 
show any header information.
The JPA store i.e. doesn't seem to have this problem, is there any 
special trick I have to use to make the headers work in Outlook?

Any suggestion would be very appreciated.

Best regards,
Thomas Söhngen

(late reply...) If JPA/Maildir... works with Outook, I guess there is
something to fix in your custom mailbox implementation.
