[tpop3d-discuss] Unable to open mailbox; it may be locked by another concurrent session

[Leon Botes]

Okay so we make exim deliver to the mailspool with permissions as such:
drwxrwx---   2 root  mail   512 Feb 25 18:59 .
drwxr-xr-x  25 root  wheel  512 Feb 18 12:33 ..
-rw-rw----   1 leon  mail   412 Feb 25 18:59 leon
Take note those that mailed me about lockfiles - there are none.

conf is as such:

listen-address: 192.168.254.10
max-children: 20

mailbox: bsd:/var/mail/$(user)

auth-pam-enable: yes

strip-domain: yes

But still the same result.

TCP Wrappers support enabled, using daemon name `tpop3d'

So i go and install another pop server (cucipop) just to check my mailboxes
are readable and all works well.

I am not spooling into domain subdirectories as yet if that makes a
difference, although it seems to be authenticating okay.

Please guys.
I 'm no GURU so answers explained would be appreciated.

That seems a surprising ownership for leon's mailbox.

... tpop3d is trying to open the mailspool as user `leon',
but that's not working out.
