Hi I'd like to report an issue I observed today for any comments people may have.
Obviously this system is going to be upgraded to a recent version (of OS and postfix), but I wanted to raise the issue for comment here in case this is unexpected behaviour. I can't find reference to it in the list archives. platform: Debian Linux (lenny), linux kernel 2.6.26-2-amd64 postfix: 2.5.5-1.1+lenny postconf -n: config_directory = /etc/postfix html_directory = /usr/share/doc/postfix/html mailbox_size_limit = 5120000000 #5-ish Gb message_size_limit = 51200000 #50Mb mydestination = <let me know if this is needed> myhostname = <let me know if this is needed> mynetworks = <ip of host>, 127.0.0.0/8, [::ffff:127.0.0.0]/104, [::1]/128 myorigin = atnf.csiro.au readme_directory = /usr/share/doc/postfix relayhost = [mailhost.atnf.csiro.au] sample_directory = /usr/share/doc/postfix-doc/examples transport_maps = hash:/etc/postfix/maps/transport What we saw in syslog was complaints from local(8) Aug 8 14:22:17 ursa postfix/local[24324]: A88FA35028: to=<hapl...@mailserver.atnf.csiro.au>, relay=local, delay=0.71, delays=0.59/0/0/0.13, dsn=5.2.2, status=bounced (cannot update mailbox /var/mail/hapless for user hapless. error writing message: File too large) A new message appeared for each new message delivery attempt. But the mailbox file size was 787Mb, well under the limit of 5Gb. This was measured with 'ls', 'du' and 'wc'. Bounce messages stating the user's mailbox was full were received by people trying to send messages to the user. Despite these messages, it seems mail continued to be added to the file, until about 14 hours later, when I intervened. The filesystem was far from full. It's ext3, on an LVM logical volume. There are no quotas set on the filesystem. lsattr on the file showed no attributes set. I tried checking for other users of the file, but invoked lsof incorrectly. Things we tried: * reload postfix * restart postfix * set virtual_mailbox_limit = 5120000000 (was not set before) and reload postfix * rename mailbox and let postfix create a new one. This last attempt worked. I checked the ulimits for the user and 'postfix', both were the same. core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 137216 max locked memory (kbytes, -l) 32 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited file locks (-x) unlimited It seems like local(8) was getting the file size wrong. Not clear to me how that is possible. Kind regards Vince
