Most of the emails I receive are now getting through, but some are getting 'stuck' in the following wallace directories (on AlmaLinux 9) and so do not appear in the users mail folders:
- /var/spool/pykolab/wallace/invitationpolicy/incoming/
- /var/spool/pykolab/wallace/resources/incoming/
The files that are getting stuck in these directories appear to be generating the following type of crash dumps in the /var/log/kolab/pykolab.log file:
2024-04-17 16:17:06,311 pykolab.wallace/modules ERROR [1329] - Module 'resources' - Unknown error occurred; UnicodeDecodeError('utf-8', b'X-Kolab-From: <<...>>', 4188, 4189, 'invalid start byte') Traceback (most recent call last): File "/usr/lib/python3.9/site-packages/wallace/modules.py", line 127, in execute return modules[name]['function'](*args, **kw) File "/usr/lib/python3.9/site-packages/wallace/module_resources.py", line 190, in execute message = Parser().parse(open(filepath, 'r')) File "/usr/lib64/python3.9/email/parser.py", line 53, in parse data = fp.read(8192) File "/usr/lib64/python3.9/codecs.py", line 322, in decode (result, consumed) = self._buffer_decode(data, self.errors, final) UnicodeDecodeError: 'utf-8' codec can't decode byte 0x96 in position 4188: invalid start byte
Exporting one of problem files to my local machine, I can re-create the problem thus:
>>> from email.parser import Parser >>> message = Parser().parse(open("/home/mike/Downloads/tmpfep6d5ue",'r')) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3.11/email/parser.py", line 53, in parse data = fp.read(8192) ^^^^^^^^^^^^^ File "<frozen codecs>", line 322, in decode UnicodeDecodeError: 'utf-8' codec can't decode byte 0x96 in position 4188: invalid start byte
Specifying a specific encoding seems to enable the parser to run without issue:
>>> message = Parser().parse(open("/home/mike/Downloads/tmpfep6d5ue",'r', encoding='latin_1')) >>>
While it appears that specifying the encode as above stop the crash, I'm not sure if this is the full or correct answer as it won't cover emails sent using a non-Western European character set.
I have package wallace-0.9.0.6-1.3.el9.kolab_16.noarch installed.
