Subject: amavisd-new: mime_decode-1 FAILED on attachments with latin-2 names
Date: Fri, 18 Feb 2011 13:08:55 +0100
Package: amavisd-new
Version: 1:2.6.1.dfsg-1
Severity: normal
Hello,
I have noticed that amavis has problem processing emails with attachments
whose name contains latin-2 character with diacritics, e.g. ecaron.
The same attachment renamed to ascii-only is processed fine.
This is what amavis logs:
Feb 18 07:42:06 bupu amavis[16497]: (16497-07) (!!)TROUBLE in check_mail: mime_decode-1 FAILED: MIME::Words: unexpected case:\n(Ry\x{0161}av\375_ Vra\x{010d}_anotace.doc) pos 0\n\tPlease alert developer.
Feb 18 07:42:06 bupu amavis[16497]: (16497-07) (!)PRESERVING EVIDENCE in /var/lib/amavis/tmp/amavis-20110218T073020-16497
\x{0161} stands for scaron (unicode hexa 0x0161)
\375 stands for yacute (iso-latin-2 octal 375, same character and code in iso-latin-1)
\x{010d} stands for ccaron (unicode hexa 0x010d)
I suspect, that the problem lies in characters encoded as \x{0000}
And this is what postfix log:
Feb 18 08:52:06 bupu postfix/smtp[28253]: 4BA6B18F42E: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=323863, delays=323863/0.02/0/0.08, dsn=4.5.0, status=deferred (host 127.0.0.1[127.0.0.1] said: 451-4.5.0 Error in processing, id=25505-14, mime_decode-1 FAILED: MIME::Words: unexpected case: 451-4.5.0 (Ry\x{0161}av\375_ Vra\x{010d}_anotace.doc) pos 0 451 4.5.0 \tPlease alert developer. (in reply to end of DATA command))
Further problem is, that amavis or postfix reports this error as temporary (451), even though
it is a permanent problem. Sender gets notified usually after few days, which is wrong.
Please help or tell me if there is some workarounrd or config option to get such e-mails through.
If more info is needed, just tell me and I'll send you what you need.

Hello,
I found out that there were installed newer modules from CPAN in
/usr/local/perl, and MIME::Words was also there. CPAN says:
cpan[7]> m MIME::Tools
Module id = MIME::Tools
CPAN_USERID DSKOLL (David F. Skoll <[email protected]>)
CPAN_VERSION 5.501
CPAN_FILE D/DS/DSKOLL/MIME-tools-5.501.tar.gz
MANPAGE MIME-tools - modules for parsing (and creating!) MIME entities
INST_FILE /usr/local/share/perl/5.10.0/MIME/Tools.pm
INST_VERSION 5.500
So it might be a bug in newer version of libmime-tools-perl, or an
incompatibility issue between mime-tools 5.501 and amavis 2.6.1.
Perhaps this bug could be reassigned to package libmime-tools-perl, and
tested with latest amavis on debian/sid.
