I am having trouble with a Telstra Dialup Internet account. Whenever I try to send an email to various accounts on more than 90% of occasions I will get a bounce back saying various things like the email was sent from an Un-Authorised IP addresss?
Then last friday I recieved a new message
An unknown error has occurred. Account: 'Bigpond', Server: 'mail.bigpond.com', Protocol: SMTP, Server Response: '500 access denied; your IP is listed by rbl-plus.mail-abuse.org.', Port: 25, Secure(SSL): No, Server Error: 500, Error Number: 0x800CCC62
I did a quick search on this so called 'spam' filter, however could not figure out how my email actually made it to this 'bad' list?
Is there any way to get your IP 'unblocked'?
