I have an email address, but in order to send email using it I need to provide my own SMTP server, i.e. that of my ISP. The problem is, I don't know what that is and the chances are they won't let me use it for any other email account than their own ones. I'm with Blue Yonder (Telewest) broadband.
I have also tried using Freeserve, which used to always work regardless of what connection you used or what email address you sent from, but it doesn't work.
Having searched for "free SMTP server" in Google several results appeared about using your own PC as the SMTP server. What security implications might this have? Does it sound like a good idea? Also, would I install it on my 2000 server (through which I connect to the net) rather than my other PCs separately?
If connecting to the internet with Blueyonder, put smtp.blueyonder.co.uk into the outgoing mail settings, regardless of the email address you use and regardless of the POP3 server(s) you retrieve mail from.
Basic rule - use the SMTP server of the ISP you are connected to the internet with.
