Bug ID: 1810
Summary: Mangled queue following system-filter unseen deliver
retry
Product: Exim
Version: 4.86
Hardware: All
OS: Linux
Status: NEW
Severity: bug
Priority: medium
Component: Delivery in general
Assignee: nigel@???
Reporter: stevep@???
CC: exim-dev@???
Following an upgrade to 4.86.2 due to CVE-2016-1531 on a couple of systems,
compiled from source, I ran into this bug using a system-filter with an 'unseen
deliver':
if first_delivery and not error_message
then
unseen deliver root@???
endif
2016-03-23 08:25:48 1agDAv-0004rt-3k == root@??? <system-filter>
R=eximtrap T=smtp_eximtrap defer (-1): smtp transport process returned non-zero
status 0x000b: terminated by signal 11
2016-03-23 08:25:50 1agDKY-0005MT-18 == root@??? <system-filter>
R=eximtrap T=smtp_eximtrap defer (-1): smtp transport process returned non-zero
status 0x000b: terminated by signal 11
This was triggered when the remote system stopped accepted delivery due to
load, and would **freeze** the undelivered messages in the queue.
I patched 4.86.2 with:
http://git.exim.org/exim.git/commitdiff/dadff1d47e54962b0fdf98e8ce5cef42b6cb7fb5
which fixed the signal 11 termination, BUT appears to mangle the message in the
spool queue. When delivery is retried (as it now should be) the -D file has
been deleted from the spool:

Although the above 1aieyV-0002ei-IR message id is marked as completed @09:22:10
on the first subsequent retry, the mail never arrives on eximtrap.XXXX.com and
the resulting 'not found' message reoccurs on queue reruns.
We were previously running a standard Debian pkg (no changes in config except
the addition 'keep_environment =' added), without issue.
I did attempt to reopen Bug 1671 - but I guess this is a different issue....
