just the channel to queue, which forwards imsgs on runner's behalf
and redirects any replies back to it.

doesn't take advantage of the new structure yet, but this was a needed
change for upcoming improvements.
- introduce aliasestree_{lookup,insert,remove} to the aliases api
- rename queue_generate_id() to generate_uid() and move it to utils.c as
it is used all over the place and not only in queue
tree idea discussed with jacekm@, if you update rebuild aliases db, make
clean and flush queue

aliases/virtual domains resolution code.
- fix a logic bug which caused virtual domains not to be correctly
handled after one iteration of the aliases resolution code.
- introduce a few helper functions to help clean up and simplify the
lka code.
- simplify the IS_EXT/IS_MAILBOX/IS_RELAY macros so they manipulate a
struct path * instead of the mess of dereferences we were passing them.

Stop pushing event handling in the imsg framework.
Instead, provide a small glue layer on top of both imsg and libevent.
This finally clearly separates event handling and imsg construction.
Sidetrack bonus: remove the mega-ugly hack of having a dummy imsg_event_add
stub in smtpctl.

process individually whenever stats need to be fetched, keep stats
in MAP_ANON shared memory allocated by parent.
This means control has direct access to stats and can respond very
quickly without troubling any other daemon processes.

and -F cmdline args. Also, date and Message-Id headers are added
when missing.
The main trouble with the current enqueue code is that it requires
dealing with problems in the control process that are already solved
in the smtp process, ie. duplicating a lot of code which interacts
with untrusted clients. This diff solves this by making sendmail
obtain a SMTP socket from smtp via smtpd.sock, and using that socket
to deliver the message. For smtpd it looks as if connection was
made from the network, only difference being the F_MESSAGE_ENQUEUED
message flag, handy when differentation between local and remote
deliveries is wanted.
Most of the features come from the femail program, created by henning@.
Additional testing by Nigel J. Taylor.
ok gilles@, henning@ happy with smtpd using femail code

the remaining code was moved to queue_shared.c; ok gilles@

1) queue never reads /queue.
2) queue writes to /queue only at message injection time.
3) runner does all reading, and all writing apart from 2).

used by queue process but also by runner, while at it change the prototype
of queue_open_message_file() so it takes the message id and not a batch,
runner process requires the decriptor before it even starts building a
batch.

provided recipient even after aliases/forwards expansion, we'll need this
for loop detection.
message id and uid being MAXPATHLEN long is a waste, define MAX_ID_SIZE
which is currently set to 64 (but can probably be further reduced) and
make sure that structures and the few strlcpy's use the right define.
original idea by jacekm@ a while ago
|

without "talking" smtp to listeners. currently, a big part of the server
side code is done (and requires a cleanup), next step is to get it usable
properly from a mail user agent.
|
|
sharedqueue.c file, smtpctl cannot link queue.o without creating a mess
otherwise. while at it, move some prototypes to smtpd.h as they will be
needed by enqueue code
|
|
we need the same functions for the enqueue code i'm currently working on.
instead of duplicating the code, add a set of functions which take the
queue we're working on as a parameter and turn the old ones into wrappers.
no functionnal change ... yet

cause delivery to happen before expansion is over, causing some of
the recipients to never receive the mail. change how the mfa, lka,
queue and smtp processes communicate to ensure smtp never receives
an acknowledgment before ALL expanded envelopes are on disk. While
at it, lka was doing work which belongs in mfa, fix that also.
this is based on an idea from a talk with jacekm@, change not over
but already better than what we had.
