Following up on my earlier mail about corrupted unix mailbox
folders after upgrading from 4.4 to 4.7a.

Have done so now and do not find any suspicious code. I use
mail_fetchbody_full() to get the contents of the individual
parts.

The problem seems to be always exactly the same: The message
content (text) starts immediately after the X-UID: XXX
header entry. instead of an empty line to separate the
header and body, I find messages like this:

[some header lines]
X-UID: 1234 beginning of
message text on same line as X-UID
[...]

These messages have been collected from an IMAP server and
stored to a unix mailbox folder, using the following bit of
code:

   STRING str;
   INIT(&str, mail_string, (void *) msg.c_str(), msg.Length());

   bool rc = ( mail_append(
      m_MailStream, (char *)m_MailboxPath.c_str(), &str)
               != 0);

Can you see anything wrong in this bit?


It's a pity that the c-client mailbxo parsing code doesn't
handle corrupted folder contents gracefully. It bombs out
from unx_rewrite_new() by calling fatal() rather than just
reporting an error and skipping that message.
