Usually message arrival, but there are settigns that can disable that in certain conditions and then one of the others is needed to cause delivery. > Or how does the delivery process > know that a message has arrived? The process that receives the message fork()s a process to do the delivery and passes it the exim_id (etc) Exim is heavily multiprocess. -- Jasen. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
Re: [exim] local delivery fails after server move
This router is ran for all your local domains. If it creates a new
address @+local_domains, there is no chance to get to the routers
further down the chain: A new address means, the routing starts again at
the very first router, and eventually it will reach your pgsql_aliases
again, which doesn't create a new address (declines), but, as "no_more"
is set, the address won't tried with the following routers.
You can either drop the "no_more" option, or, if the outcome of the
pgsql_aliases can *always* be handled by the routers further down in the
chain, you can use "redirect_router = userforward" in your pgsql_aliases
routers.

I susppect you may e thinking there is only one, long-lived, delivery process - which does all deliveries. That isn't so. A process is started when a delivery is needed. It does what it can, which might handle more than one message, and then terminates. There could be multiple delivery processes running in parallel, and there could be none at all, at any given moment. -- Cheers, Jeremy -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
Re: [exim] who starts the delivery process?
This is a theoretical question, I write exim instructions. The documentation says that there are four types of processes: 1. The daemon process 2. Reception processes 3. Queue runner processes 4. Delivery processes With respect to the first three, everything is clear, the main process starts the second and third. The fourth is launched by the third and admin, the question is who starts it when the message arrives? пн, 26 дек. 2022 г. в 15:33, Niels Kobschätzki : > Maybe you should tell us what you want to do. > > Best, > > Niels > > On 26.

The question is the following: Can you tell me who starts the delivery process when a message arrives? Or how does the delivery process know that a message has arrived? Thanks in advance for your reply. First a few key facts: 1. There is only one Exim binary 2. Exim typically has one or two daemons running, if two then one listens on SMTP port(s) and the other only launches queue runners periodically. 3. Since there is only one binary, all exim processes are the same binary executed with different command-line options and sometimes as different users. Starting a delivery process simply means exim starts a new exim process with the relevant command-line options. For local deliveries, the delivery process will also change to the user ID of the recipient. The process does the delivery and then exits. When an SMTP connection comes in, exim forks rather soon. We now have a process handling that SMTP connection. Once a message has arrived, and it's time to attempt a delivery, that process will start the delivery process, not by just forking but by executing a new exim process, to allow for changing privileges. Only the daemons are long-running. All other processes are started for a certain task and they exit when it is done. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/

[exim] who starts the delivery process?
Helo I found in the documentation: Delivery processes may be started as a result of a message’s arrival, by a queue runner process, or by an administrator using the -M option. The question is the following: Can you tell me who starts the delivery process when a message arrives? Or how does the delivery process know that a message has arrived?
