I have seen such behaviour with broken firewalls (somewhere on the way, could be on yours or their side) which erroneously tried to handle tcp window scaling (rfc 1323). Are they/you using Linux with kernel > 2.6.17? Then try "echo 0 > /proc/sys/net/ipv4/tcp_window_scaling". See e.g. http://kerneltrap.org/node/6723 for more information. -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
