SMTP Mail

[dyanamo]

Anyone know any free SMTP servers like smtp.saix.net in SA? I have used PHP and telnet and always when I put in the recipient I get the following error "554 : Sender address rejected: Access denied". This happens no matter what recipient address I put in. Is there away around this or prehaps another free SMTP SA based server? Also to mention when I use the built in PHP mail function using smtp.saix.net it works but this meathod is to insecure for the application im developing.

Depends whats the source IP that initiates the connection. Be it your website provider's upstream provider or your own internet connection.

Each ISP has its own open SMTP relay so to speak. But you can't use a diff isp to your own's relay

You will most likely not be able to use another ISPs SMTP server, but your ISP will provide you with an SMTP server than you can use...

Alternatively (if you are running Linux), you could install something like postfix, which you can use to have full control. However, you may receive some issues with spam filters (on the receiving end) if you are sending from a dynamic IP address, or one that is registered as a known spam source.
