Hi,

one of our remote servers (outside our main datacentre) cant connect to our webserver's mailserver at
ns1.uservenet.com **try "telnet mail.plugpayplay.com 25" **

I can connect to that mailserver on port 25 from my location:

# telnet mail.plugpayplay.com 25
Trying 89.145.94.11...
Connected to plugpayplay.com.
Escape character is '^]'.
220-ns1.uservenet.com ESMTP Exim 4.69 #1 Mon, 18 Jul 2011 19:41:25 -0400 
220-We do not authorize the use of this system to transport unsolicited, 
220 and/or bulk e-mail.
quit
221 ns1.uservenet.com closing connection

This sounds like a firewall issue on the remote machine that is trying to connect to that mailserver. You should try taking down the firewall or ensuring it has port 25 outbound open when trying to telnet from it to the mailserver.
