opendkim fails

[rTiGd2]

Am I missing something?

2023-11-03T14:10:26.995402+00:00 WARNING postfix/smtpd[424]: warning: host or service localhost:8891 not found: Temporary failure in name resolution
2023-11-03T14:10:26.995415+00:00 WARNING postfix/smtpd[424]: warning: connect to Milter service inet:localhost:8891: Cannot assign requested address

If I enable auto keys, or generate my own, everything breaks. If I remove all dkim stuff, then I can send but get spam jailed everywhere.

I'm fairy certain that I have configured this properly (I mean, you put some files in a place, right) was there some voodoo that isn't in the documentation ?

Sorry, I'll need more info about this -- how exactly are you running the image:

• what's the configuration
• Helm / Docker
• version
• ....

Until I have more info to replicate the issue, it's going to be difficult for me to help you.

Nevermind, I rolled my own container as I needed to go home today.

Same here. v3.6.1 is working but v4.0.1 milter/dkim fails.

sudo docker run -d
--name postfix
--restart=unless-stopped
-e TZ="Europe/Zurich"
-e ALLOWED_SENDER_DOMAINS="redacted.com"
-e RELAYHOST="host:587"
-e RELAYHOST_USERNAME="redacted"
-e RELAYHOST_PASSWORD="redacted"
-e POSTFIX_smtp_tls_security_level="encrypt"
-e POSTFIX_myhostname="myhostname"
-e POSTFIX_message_size_limit="10485760"
-e DKIM_SELECTOR="mail"
-e DKIM_AUTOGENERATE="true"
-p 587:587

boky/postfix:$VERS

Ok, this is a similar issue to #147. The default image was changed from Alpine to Debian. People who have mounted configuration folders have encountered issues because Alpine and Debian keep files in different places.

I have not encountered this error because I don't mount previous version's folders into the image (in fact, you don't need to mount /etc/postfix in most cases).

I will retest and let you know.

I cannot replace this issue even with configuration files from v3.6.1:

This is from within the container:

docker exec -it clever_solomon bash -c "netstat -taupen"
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       User       Inode      PID/Program name
tcp        0      0 127.0.0.1:8891          0.0.0.0:*               LISTEN      101        11310415   -

These are the last lines from the log:

2023-12-29 15:01:35,521 INFO success: rsyslog entered RUNNING state, process has stayed up for > than 2 seconds (startsecs)
2023-12-29 15:01:38,531 INFO success: opendkim entered RUNNING state, process has stayed up for > than 5 seconds (startsecs)

So, OpenDKIM is running. I would need more info. Can you share startup logs, perhaps?

Did you start a fresh install (empty configuration folders) with v4.0.1? That's what I did but no success.

[bokysan]

Fresh install (empty configuration folders) works as well over here, using the following script:

#!/bin/sh
# Save this to test.sh
VER="$1"
DIR="$(pwd)/test"
mkdir -p "${DIR}/spool" "${DIR}/etc" "${DIR}/keys"
 docker run \
    --pull always \
    -e ALLOWED_SENDER_DOMAINS="redacted.com" \
    -e TZ="Europe/Zurich" \
    -e RELAYHOST="host:587" \
    -e RELAYHOST_USERNAME="redacted" \
    -e RELAYHOST_PASSWORD="redacted" \
    -e POSTFIX_smtp_tls_security_level="encrypt" \
    -e POSTFIX_myhostname="myhostname" \
    -e POSTFIX_message_size_limit="10485760" \
    -e DKIM_SELECTOR="mail" \
    -e DKIM_AUTOGENERATE="true" \
    -p 587:587 \
    -v "${DIR}/spool:/var/spool/postfix" \
    -v "${DIR}/etc:/etc/postfix" \
    -v "${DIR}/keys:/etc/opendkim/keys" \
    --rm -it boky/postfix:$VER

./test.sh latest

I did an upgrade to 4.0.2 but keeping my files/folders. It seems everything is ok now.

Closing issue. If it pops up again, please provide additional info and reopen.
