Subdirectories in /var/log/delivery ended with wrong ownership

[Pim van Riezen]

The SMTP component of poste.io stopped accepting inbound mail with no clear reason. The underlying reason seems to be that some of the date-specific files in /var/log/delivery inside the container spontaneously changed ownership to root:

After changing ownership of all files to delivery:mail, the smtp server started working again. But these ownership changes were not instigated by me, nor was it apparent from the web ui that there was a problem.

Do you have latest version?

Please try the latest one (released today). There is an awful NodeJS bug that corrupts the delivery directory with files owned by root that are not available to the mail:mail process.

Older files can be fixed with chown 88:8 /data/log/delivery -R
