Thank you Wietse,
I followed your advice and ran a strace on the smtpd process.
Postfix is running in a chroot environment (/var/spool/postfix) and I
noticed the following:
Dec 27 16:55:05 85b8d58a343c root: open("/etc/resolv.conf",
O_RDONLY|O_CLOEXEC) = 18

Hi Wietse,
Thank you for your answer.
The docker containers are running Debian 9.3 and the postfix package
from the official Debian repository (Version: 3.1.6-0+deb9u1).
As you can see below the source code still contains calls to
gethostbyname():
postfix-3.1.6~ fgrep gethostbyname . -R -

Hi all,
I'm currently trying to dockerize my mail server environment and
encountered a strange issue on which I spent some time to debug.
I have several docker containers running different components:
- postfix (172.20.0.4): postfix 3.1.6-0+deb9u1
- dovecot (172.20.0.5): dovecot 1:2.2.27-3+deb9
