Why do I get a relaying denied message when trying to receive data back as an email response?
Due to widespread email “Spam”, most mail servers are unable to operate an “open relay” that would allow anyone to send mail from their servers. Instead they use “POP Authentication based selective relaying”. When you authenticate via POP3, your IP address is added to a list of IP addresses that are temporarily allowed to relay through without restrictions. As long as you check your mail before sending, or at least once every few hours, you can usually be sure your IP address is in the list of allowed relay clients. If this fails to resolve the issue, you will need to talk to your mail provider for assistance, explaining what you are doing eg. sending mail from a script using their SMTP gateway.
