Reading and writing Mozilla-mail in python

[Uwe Grauer]

Hi all,

who can help on reading and writing mozilla-mail folders with python?
I wanted to implement something like an email-sync for mozilla-mail in
python. I did some tests, but something is strange with the email
(rfc822) modules in python. (The output of parsed messages is different
from the original input)

Any hints of how (what modules) this could be done in a portable manner?

Thanks,
Uwe

What format are they? mbox?

Some tools to do this already exist. Check on packages.debian.org. I
think one of them is called 'offlineimap' and is implemented in
python.

Use the 'email' module for handling individual email messages (not
rfc822). Note that both of those modules only process one message at
a time, not an entire mailbox.

After playing around with the mailbox an email modules i noticed some
strange behaviours:

after the first message is parsed, i got some (kind of parsing errors).

My code:

def test_copy(infile, outfile):
from mailbox import UnixMailbox
from email import message_from_file as mff
try:
fd = open(infile, 'r')
try:
for message in UnixMailbox(fd, mff):
print message
print '***********************************************'
finally:
fd.close()
except:
pass
return

output from script above:

Nein, leider noch nicht, komm auch erst in paar Tagen dazu.

Could someone please verify this?

Now i tried it under Linux (Suse 8.2) + self compiled python 2.3.2.
It works!!
So, what the hell is going on with my stupid win2000?

Has anyone seen this before?

It think i'm going to reinstall the whole Shit.

maybe opening the file in binary mode helps (i.e. open(infile, "rb")) ?

Ralf is correct. The UnixMailbox method uses tell and seek to remember
file locations and return to them later. Tell and seek on Windows are only
valid with binary files; the \r\n to \n translation screws it up.

Change that to
fd = open(infile, 'rb')
and all will be well.

seek/tell works just fine on text files, as long as you only seek to
positions returned by tell (or to the beginning of the file). This is
standard ANSI C behaviour, btw.

(from a quick glance at the mailbox code, I cannot find any case
where the mailbox doesn't use seek/tell in this way, but I might be
missing something...)

Indeed, you are right.
