We played around and found that the error is related to our version of
Python. Here's a minimal test script that shows the issue:
from email.Utils import parseaddr, parsedate_tz, mktime_tz, formatdate
print mktime_tz(parsedate_tz("Fri, 4 Feb 100 00:51:42 +0100 (MET)"));
That's the Date header from the single piece of legitimate mail. Python
2.4 throws the same exception you were seeing: "ValueError: year out of
range". However, our Python 2.7 (which we use for Mailman) does this:
-59008522098
When that value is then passed to time.ctime(), you get "ValueError:
timestamp out of range for platform time_t". We're on RHEL 5, and our
version of Python 2.7 is from the IUSCommunity repo:
python27-2.7.10-1.ius.el5. Which version of Python were you using?
Thinking about this a bit more, I think what you say is the crux of the
difference between yours and mine. In your Python,
time.ctime(-59008522098) throws the ValueError, and in mine it returns a
date string which may cause problems later on in the processing.
I think the difference is not with a Python version per se, but rather
with the underlying C environment and C library 'time' functions that
Python was compiled with.
That makes sense.
In any case, I think I now have enough understanding of the issue to
work up some kind of fix that will work in both your situation and mine.
Note that your original suggested patch won't solve the problem for me
because my time.ctime(-59008522098) does not throw a ValueError.
Right. Of course I didn't know that at the time :-)
Unless you're really interested in the other differences you referred to in
your other message, I won't bother to analyze them further. It seems clear
to me that you have identified the main issue.
Thanks for your help!
