Summary: "(un)seen deliver" command (system filter) makes message
"complete" prematurely
Product: Exim
Version: 4.67
Platform: x86
URL: http://lists.exim.org/lurker/message/20080619.095806.04b
30cb1.en.html
OS/Version: Linux
Status: NEW
Severity: wishlist
Priority: medium
Component: Filters
AssignedTo: nigel@???
ReportedBy: dominik.schramm@???
CC: exim-dev@???
Overview:
The recipients added by a deliver command in a system filter are silently
dropped under certain circumstances, if the first delivery attempt fails.
Steps to Reproduce:
1) minimal system filter:
if not first_delivery
then
finish
endif
if $recipients is order@???
then
seen deliver copyaddress@???
headers add "X-test-header: test"
endif
2a) Have a local DNS serve non.existent.domain and refer to a
non-existing MX (sending TCP packets to that MX into nirvana):
non.existent.domain IN MX 10 mx.non.existent.domain
mx.non.existent.domain IN A 10.1.1.1 (non-existent!)
Alternatively:
2b)
Have the firewall drop packets to the non.existent.domain MX (sending
TCP packets to that MX into nirvana).
3) Send message to other@???. The destination mail server will
be unreachable, so after the timeout the message will be on the queue as
follows:
2m 0.1K 111111-222222-XX <sender@mydomain>
D order@???
4) After the initial delivery attempt the log file says:
111111-222222-XX == copyaddress@??? <system-filter>
R=dnslookup T=remote_smtp defer (110): Connection timed out
Then force a delivery retry of message 111111-222222-XX.
Actual Results:
The message disappears from the queue (because of "finish"?),
the following is logged:
111111-222222-XX Completed
Expected Results:
The message should remain on the queue and be retried according to the
rules until the destination mail server can be reached or the usual final
timeout occurs.
Ideally a whole new message should be put on the queue by the deliver
command -- specifically to make it clearly visible that a new delivery
is in progress and to make the new sender and recipients visible -- which
keeps a certain relation with the original message so that the usual filter
behavior remains unaltered.
