Hi,
I am trying to install tpop3d on a Gentoo Linux with Maildir support. =
Here is my conf:
listen-address: 0.0.0.0
max-children: 10
strip-domain: yes
timeout-seconds: 60
mailbox: maildir: $(home)/Maildir
tcp-wrappers-name: pop3
auth-passwd-enable: yes
Here are the interesting parts of tpop3d -h:
tpop3d # tpop3d -h
tpop3d, version 1.4.2
......
Available authentication drivers:
auth-pam Uses Pluggable Authentication Modules
auth-passwd Uses /etc/passwd or /etc/shadow
auth-mysql Uses a MySQL database
Available mailbox drivers:
bsd BSD (`Unix') mailspool
maildir Qmail-style maildir
empty Empty mailbox
This tpop3d has TCP Wrappers support.
.............
And finally here is the log from a failed session:
TCP Wrappers support enabled, using daemon name `pop3'
listener_new: gethostbyaddr(0.0.0.0): cannot resolve name
listener_new: 0.0.0.0: no domain suffix can be appended for this address

--------- Cut --------------- Cut =
-------------------------------------------------------------------------=
--------------------------------------------------
I have tried to install tpop3d v1.5.2 but got the same results. Even =
more interesting is the thing that on another serverthe exact same =
configuration=20
works with the exact same version of tpop3d with no problems at all. The =
only significatn difference that comes to my mind is that the /home is =
on a
ResiserFS where it works, while here is Ext3. But I can't imagine how =
this can be a problem.
I saw a prevous post of someone troubled by the same thing, but the =
answer was something like "Check your maildir for a *.lock file".
Well I don't have one (*.lock file I mean). And I'm pretty sure that =
there are no concurrent pop3 sessions.
Any ideas?
Regards,
Emil Filipov
