I am using windows live mail and when I send an email it is going into my sent file but is not being received.  When I send an email on my phone using the same account it works fine.  The message I have been getting on Live is;

Server Error: 421

Server response: 421 nskntcmgw06p BigPond outbound connection refused too many sessions from 101.182.46.30. OB007

Server. mail.bigpond.com

Windows Live Mail Error ID 0x800CCC67

Protocol SMTP

Port 25

Can someone help please?
