I believe this is not an Exim-problem, but you can:
1) Take down the DNS and the exim machine, start sniffing on the host,
power up the exim machine:
# tcpdump -i eth? port 53
# start exim-machine
to see what it is querying, add those entries to /etc/hosts in the
exim-machine
and "supposedly" no more delays are going to occur.

Hello:
My box runs Devuan Beowulf and within it runs a (VBox) Devuan ascii
virtual machine set up
to start up automatically when I boot.
It is not kept on 24/07 but is booted up a few times every 24 hours.
The Devuan ascii virtual machine runs PI-Hole as a recursive DNS
server.
It is all working as it should but there's a 'snag in the weave' so to
speak:
When booting, I'm getting a (not too) short delay at "Starting MTA:"
which is when (as I
understand it) Exim4 does a reverse DNS check.
The problem is that my DNS (unbound) runs on the Devuan ascii virtual
machine which I set
up to start up automatically at boot but it is not yet up and running
when Exim4 does the
reverse DNS check.
Hence the delay (30/40s?) I am refering to.
Exim4 is set up to receive "local delivery only; not on a network",
listens only to IP 127.0.0.1
for incoming SMTP connections and accepts my box's user as the only
other destination for
which mail is accepted.
As I am on a wired ADSL connection and have "always on" web access,
"Dial-on-Demand"
configuration is disabled.
Is there a way I can avoid the "Starting MTA:" delay at boot?
Thanks in advance,
JHM
