exim4 socket bind() failed as single installed MTA

Hi,

I'm using here debian/testing i386. The problem is related to exim4:

$ cat /var/log/exim4/paniclog
2006-08-30 17:32:05 socket bind() for address 127.0.0.1 failed: Address
already in use: daemon abandoned

even if:

$ netstat -lpn|grep :25
tcp 0 0 127.0.0.1:25 0.0.0.0:*
LISTEN 5701/exim4

The error message shows up on bootstrap also and the 'mta' needs time to
start (I guess a timeout) and failed then.

I did not configure exim4 (v4.62-4) by hand yet - only dpkg-reconfigure
exim4-config to use local email. What is the relevant part of exim's
config files here which I can post here (there a lot)?

Using google I found a hint related to (x)inetd which isn't true for my
case:

$ grep -v "^#" /etc/inetd.conf
ident stream tcp wait identd /usr/sbin/identd identd

Maybe of interest is also:
$ dpkg --get-selections |egrep '(exim4|mail|mta)'
exim4 install
exim4-base install
exim4-config install
exim4-daemon-light install
libmailtools-perl install
mailx install
procmail install


The interesting thing is that local mail transfer is working (not
tested immediate after booting debian) but these error message is confusing.

Thanks
Olaf

It looks like exim is failing to start up because it's already running.
Perhaps two different things are trying to start it. It may help to do
something like:

find /etc -type f -exec grep -H exim {} \;

I've got of interest:

What does the ip-up.d/exim4 script do?

$ find /etc -type f -exec grep -H exim {} \;

$ cat /etc/ppp/ip-up.d/exim4
#!/bin/sh

if [ -n "$EX4DEBUG" ]; then
echo "now debugging $0 $@"
set -x
fi

[ -x /usr/lib/exim4/exim4 ] || exit 0

is set in /etc/default/exim4. Further more my
$ cat /etc/network/interfaces

mapping eth0
script grep
map eth0

iface eth0 inet dhcp

where no ppp is set.
