Connected_to_< Remote IP >_but_connection_died

[cosito]

Hello,

if our server is sending large files mail to a spezific host, we got the error "Connected_to_< Remote IP >_but_connection_died" in /var/log/mail.info

Other servers are able to send large emails to this server. I made a tcpdump, without any result.

I don't know what to do.

please help

Yes, you have to enable

ip_contrack_tcp_be_liberal

we did this by creating a file /etc/ppp/ip-up.local with following lines:

#!/bin/bash
echo 1 > /proc/sys/net/ipv4/netfilter/ip_contrackk_tcp_be_liberal

This will enable the option on startup in SuSE 10.0

Ok. Worked for me.
Also had to change other conntrack settings.
