hi
on iRedMail-0.9.7 + Pro V2.7 running on Debian v7.11 - upgraded since well since forever

same issue here:
/usr/share/apache2/iredadmin/tools# python notify_quarantined_recipients.py --force-all
* 235 users are willing to receive notification email.
Traceback (most recent call last):
  File "notify_quarantined_recipients.py", line 301, in <module>
    time_tuple = time.strptime(time_with_tz, '%Y-%m-%d %H:%M:%S')
  File "/usr/lib/python2.7/_strptime.py", line 467, in _strptime_time
    return _strptime(data_string, format)[0]
  File "/usr/lib/python2.7/_strptime.py", line 322, in _strptime
    found = format_regex.match(data_string)
TypeError: expected string or buffer

I suspect - but can only guess that some domains have a defined timezone in their settings and some (most) don't and I guess this fails.

well, so I take my debugging hat and analyze the issue:

I added a "print time_with_tz" after "time_with_tz = utc_to_timezone(dt=dt, timezone=settings.LOCAL_TIMEZONE)"

and added some error handling as well as type conversion to string for the for the value returned by utc_to_timezone:

        # hk debug:
        print time_with_tz

        try:
          time_tuple = time.strptime(str(time_with_tz), '%Y-%m-%d %H:%M:%S')
          print (time_tuple)
        except ValueError as err:
                print(time_tuple,err)

this is a step forward, but when it comes to mail_body generation we hit another roadblock:

Traceback (most recent call last):
  File "notify_quarantined_recipients.py", line 347, in <module>
    mail_body = mail_body_template % {'quar_mail_info': quar_mail_info.encode('utf-8'),
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 119: ordinal not in range(128)

Please try this fix:

Here are the news:

Error still there. Because there where no mails quarantined the error won't occour.
So yesterday I got the error again because of 2 SPAM mails.

I looked through the notify_quarantined_recipients.py and compared it with the previous version (2.8.0) and found that there maust be a problem with the time-zone converting:

        dt = datetime.strptime(time_iso, '%Y%m%d%H%M%S')
        time_with_tz = utc_to_timezone(dt=dt, timezone=settings.LOCAL_TIMEZONE)
        time_tuple = time.strptime(time_with_tz, '%Y-%m-%d %H:%M:%S')
       

So for a quick repair I commented the lines out and changed them back to the 2.8.0 version:

        time_tuple = time.strptime(time_iso, '%Y%m%d%H%M%S')
        mail_date = time.strftime('%b %d, %Y', time_tuple)
        mail_time = time.strftime('%H:%M', time_tuple)

Tested with http://www.emailsecuritycheck.net/index.html and I got the mail ([Attention] You have 7 emails quarantined and not delivered to mailbox) and nor error at all.

Maybe this helps a little bit.

For now I am happy with this workoround.#

Hi,

I've inserted some print commands:

dt = datetime.strptime(time_iso, '%Y%m%d%H%M%S')
        print "dt= ", dt
        time_with_tz = utc_to_timezone(dt=dt, timezone=settings.LOCAL_TIMEZONE)
        print "time_with_tz= ", time_with_tz
        time_tuple = time.strptime(time_with_tz, '%Y-%m-%d %H:%M:%S')
        print "time_tuple=", time_tuple

output:

root@mail:/opt/www/iredadmin/tools# python notify_quarantined_recipients.py --force-all
* 24 users are willing to receive notification email.
dt=  2017-08-13 13:45:21
time_with_tz=  2017-08-13 13:45:21
