I have about 8 of these over two days all continue to be retired
I am trying to be pro-active and was just looking if ether was something i may
have hosed on my side
although this is the only server I have been having problems
I really think the issue is with that server but was just looking for expert
input
try "net.ipv4.tcp_window_scaling = 0" in sysctl.conf and "sysctl -p",
maybe they have some crap device in front of their server!

I am having trouble sending email to a specific server
I got the following error
"lost connection with
mx.example.org [xx.xx.xx.xxx] while receiving
the initial servergreeting”
The operator says its my issue yet i have no problems with any other servers
that is nonsense because he can't know that - no other complaints don't mean it
happens here and there without take notice not does that message alone means
anything at all
"lost connection" is just the messenger that, well, the connection was lost and
is completly outside postfix scope, the only relevant question is how often that happens
and if a lter retry works which is expected behavior
look below 8 lost connections to one server of hotmail
so what - 12 successful - the first was retried seconds later to a different
MX, the reason could have been our link, their link, one of the routers between
the servers at that moment - who cares?
so did your mail *really* fail or do you just have panic because you see "lost
connection" for no reason?
