My postfix incoming folder at /var/spool/postfix/incoming (within chroot) on a debian squeeze instance is filled with a bunch of stange files that are not removable, stat'able, chmod'able or whatsoever:
drwx------ 2 postfix root 4096 Nov 19 16:18 .
?????????? ? ? ? ? ? 019E310000B9
?????????? ? ? ? ? ? 0775C1000081
?????????? ? ? ? ? ? 0874F1000082
?????????? ? ? ? ? ? 180E41000083
[...]
$ file 019E310000B8
019E310000B8: ERROR: cannot open `019E310000B8' (Invalid argument)
$ cat 019E310000B8
cat: 019E310000B8: Invalid argument
$ rm 019E310000B8
rm: cannot remove `019E310000B8': Invalid argument
Additionally, my mail.log shows entries like the following for the files mentioned:
Nov 19 16:22:20 mail postfix/qmgr[1506]: warning: incoming/019E310000B8: Invalid argument
Nov 19 16:22:28 mail postfix/showq[1585]: warning: incoming/019E310000B8: Invalid argument
Does anyone have a hint for me what could be wrong? I am a bit helpless...
Thanks in advance :)
