[rolo2912]

For the last 2 days I am getting this error message from postfix.

Its not related to only one domain and seems to come up random.

The queue is empty (postqueue -p | grep Results)

 

Sufficient disk space is there.

 

No changes in the postfix rights.

 

I am a bit clueless to what is causing the problem.

 

I know it is stupid, but I restarted the server 2 hours ago and didnt

get any more of these errors. Dont know if this fixed the problem. suppose not.

 

Any hint is welcomed.

 

Thank you.

queue write error sounds like permission issues to me. Your config looks fine to me.
