Subject [jira] [Resolved] (JAMES-1222) JAMES hangs on mails with 8-bit characters in headers
Date Tue, 03 May 2011 11:33:03 GMT

     [ https://issues.apache.org/jira/browse/JAMES-1222?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Norman Maurer resolved JAMES-1222.

       Resolution: Fixed
    Fix Version/s: 3.0-M3

I was finally able to track down the problem. Thanks again for all your help. The problem
was not really limited to messages with 8-bit chars in headers, as it could happen with other
messages too. 

I fixed it in now in current trunk. If you plan to upgrade to it you will need todo some extra
step for the upgrade as the mailbox jpa tables had changed. You will need to copy all your
mailboxes to maildir (or jcr), then upgrade. After the upgrade was done just copy the mailboxes
back to jpa. All this can be done via jmx.

>             Project: JAMES Server
>          Issue Type: Bug
>    Affects Versions: 3.0-M3
>         Environment: Windows XP
>            Reporter: Dmitry
>            Assignee: Norman Maurer

> RFC 2822 and RFC 2047 require that all characters in headers with codes above 127 must
be encoded. But more then 10 percent of real e-mails have 8-bit-characters in headers (not
only spam! very popular forum engines send 8-bit headers in mails). 
> If JAMES has received such mails with 8-bit characters in headers and they are on server,
I can not get ALL mails (RFC compliant and not compliant) through POP3: error 0x800CCC19 in
Outlook Express (timeout) or error 0x8004210A in MS Outlook ('The operation timed out waiting
for a response from the receiving (POP) server...') 
> Through IMAP I get all mails. Messages that are not compliant to RFC have question marks
in their headers in IMAP folders.
