Comment(by Thasaidon):

 I'm using WinXP SP3 and Ubuntu Linux 8.04, both with Pidgin 2.6.2
 And MSN users have reported the same problem to me while I'm using either
 OS.
 So it seems the problem is pidgin related, not OS related.
 Also, I do not get any errors what so ever. It's the MSN users who get the
 "The following message could not be delivered to all recipients" error.

 Furthermore, the problem exists when connection to the internet via a
 proxy (at work), but also when connecting whithout a proxy (at home).
 However, with or without a proxy, there is always a NAT router/firewall
 between the host system and the Internet.

 Changing my LAN ip to my actual public ip, does not help.
 Enabling/disabling "automatic router port forwards" does not help.
 Enabling/disabling "Use HTTP Method", does not help.

 I am assuming that there is some kind of session time-out set in pidgin?
 If so, the most plausible reason would be that the NAT translations on the
 router/firewall will timeout resulting in a "loss of connection", because
 Pidgin is not keeping an open (active) connection.

 The only thing I have not tried is:
 Manual specification of "range of ports to listen on", with the
 appropreate portforwarding on the router/firewall.
