Hi experts,

I am writing Python code to process e-mails. This code only processes new e-mails. Whenever it finishes processing a new e-mail, it should update "Status". However, my code fails to do so. Anybody knows how to fix it?

Thanks so much.

mbox = mailbox.mbox('/var/spool/mail/' + user)
                for key, msg in mbox.iteritems():
                        flags = msg.get_flags()
 
                        if 'R' not in flags:
                                # process e-mails here
                                         try:
                                                msg.set_flag('R' + flags)
                                                mbox[key] = msg
                                                msg.flush()
                                        except:
                                                print "error in save 'R' info!"

two changes at lines 8 and 10:
at line 8 the method name is wrong, the correct is set_flags
at line 10 flush() is a method of mbox and not msg
mbox = mailbox.mbox('/var/spool/mail/' + user)
    for k, msg in mbox.iteritems():
        flags = msg.get_flags()
        if 'R' not in flags:
            # process e-mails here
            try:
                msg.set_flags('R' + flags)
                mbox[k] = msg
                mbox.flush()
            except:
                print "error in save 'R' info!"

Hi ilalopoulos,

Thanks so much for your reply. Following your suggestions I have modified my code, however this time I got an except "error in save 'R' info!". Further investigation led to the code
mbox.flush()
"Operation not permitted".

I also got this error once "I/O operation on closed file". It seems to me that I should open that mail file explicitely.

I googled online however I did not find a clue how to fix it. Do you have any ideas about this?

Thanks again.

Check your permission rights to act on the files or execute your script with sudo i.e.:

sudo python your_script.py
