Hello,

I am trying to make the local delivery wait for the previous local
delivery to be finished before continuing.

After I read the pipe(8) manual, "RESOURCE AND RATE CONTROLS", I defined
these in my main.cf:

mailbox_transport = cyrus
cyrus_destination_concurrency_limit = 1
cyrus_destination_recipient_limit = 1

BTW, the two last settings do not show up in the output of "postconf
-n", I do not understand why. See at the end for the complete output.

The "cyrus" transport is defined in master.cf as this:

cyrus unix - n n - - pipe
user=cyrus argv=/home/cyrus/bin/deliver.run ${user} ${sender}

"deliver.run" is a custom shell script which calls "spamc", then Cyrus
deliver.

Looking at the logs, the destination_concurrency_limit does not seem
respected. Here is a sample, where I can see that the processing of a
new message starts before the previous one completed.
