postfix queue file write error after container restart

[MHofer]

after restart the container the mailserver ist dead, postfix error ist "queue file write error" after create the container it works

[iredmail]

Did you lose the mounted volumes after restart?

[MHofer]

the folders are connected but they are empty

after a recreation they also remain empty but the server is working

[tpimh]

For some reason, the restart always fails. I just first remove the container (preserving the volumes), then recreate it, and it starts well.

[MHofer]

I had an error with the volumes, which I have corrected, but I still have to recreate the iRedmail container after restarting the server.

[iredmail]

Do you guys run iRedMail Docker with poetainer or any other tool?

[MHofer]

i use portainer 2.11.1 and the stable tag

[iredmail]

Did you add any arguments / settings in Portainer to start this container?

[tpimh]

I just tried with Portainer, and I can reproduce the issue.

Here is my slightly redacted docker-compose yaml:
