[jira] [Commented] (JAMES-1222) JAMES hangs on mails with 8-bit
characters in headers
[ https://issues.apache.org/jira/browse/JAMES-1222?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13027501#comment-13027501 ]
Dmitry commented on JAMES-1222:
-------------------------------
I scanned the pop3 session for the mail with question marks in the headers. I attached the results in the file 'wireshark_UTF-8.txt'. Character encoding of this file is UTF-8.

> Key: JAMES-1222
> URL: https://issues.apache.org/jira/browse/JAMES-1222
> Project: JAMES Server
> Issue Type: Bug
> Affects Versions: 3.0-M3
> Environment: Windows XP
> Reporter: Dmitry
> Assignee: Norman Maurer
> Attachments: mail.txt, mail_UTF-8.txt, wireshark_UTF-8.txt

> 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.
