I recently moved out mail operations to a new server. The old server
is
running Postfix 2.8 and the new server 2.10.
We had some initial problems with some private blacklists and the new
IP
but those were resolved. However, I had a curious problem sending
mail
to icloud.com addresses. Postfix was reporting:
lost connection with mx5.icloud.com.akadns.net[17.172.34.68] while
receiving the initial server greeting
to all MX servers for adadns.net.
What is your servers's public IP address? I suspect that PTR
or A lookups are taking too long when the remote SMTP server is
trying to determine your server's hostname.

It doesn't seem to be taking long (from 3rd party location 191 msec) and
wouldn't that have affected as well dong a telnet?
