Postfix/bounce error

[vsupport]

We are getting these errors lately
Any ideas?


Aug 18 08:18:18 pmg3 postfix/bounce[304344]: warning: [built-in]: zero result in delay template conversion of parameter "maximal_queue_lifetime_days"

 

[Stoiko Ivanov]

I guess you have some modification to the postfix configuration (probably to settings for the queue lifetime) - in that case it might be that the setting is too low...
please provide:
* any modifications to the configuration you did (probably through a template in /etc/pmg/templates)
* pmgversion -v

 

[vsupport]

Have not modified any templates

The only changes we have made is to

add a queue monitor ( code found here on forum)
add subject to syslog
turn on rsyslog to combine all 3 of our nodes logs so that tracking center shows all 3 nodes.

please show your:
/etc/postfix/main.cf
/etc/postfix/master.cf

...

 

[vsupport]

Here are the files..

 

[Stoiko Ivanov]

the line:

maximal_queue_lifetime = 8h

in main.cf causes the warning - and this is not in the shipped template - so I'd assume you have added to a template override - see the reference documentation:
https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmgconfig_template_engine

additionally it seems as if your template does not include the latest changes shipped by us (you can compare your template to /var/lib/pmg/templates/main.cf.in)

I hope this helps!
