empty pid files

[Dominic Raferd]

I used to run postfix chrooted but no longer do so.

|find /var/spool/postfix -type f -ls|

shows a list of files in /var/spool/postfix/pid/ with names inet.* and
unix.*, all very old and zero-length. Is this a hangover from running
postfix chrooted? Can I remove them all?

It also shows a few files in /var/spool/postfix/defer, some a few days
old others much older. |postqueue -p| reports 'Mail queue is empty'.
Question ditto.

I should have said there is also a non-zero and newish file
|/var/spool/postfix/pid/master.pid| which I presume should stay.

You can delete these files safely only after Postfix is stopped.

Thanks Wietse. Most of (or perhaps all) the pid files were recreated
anyway when, or shortly after, postfix restarted.
