Setting up a Mail Server

Hi

I use a mail server to combine all my families email accounts into three accounts but what to send out directly to the recipents mail server but for some recipients mail servers get the message "Socket connection closed by the other side (how rude!)". Some on the Internet suggest the problem is DNS related. I do not host a domain. If I switch back to using Plusnet it passes the email to relay.plus.net ok. If anyone has any idea why some mail server reject my attempt to send please let me know. The full session information is

Setting up a Mail Server

You don't need a mail server to do this; all you need is a separate login to your machine for each member of you family. They should all be configured to use relay.plus.net for sending email, and have their own mailboxes on PN.

You mail server is probably not accepted by the other mail servers because it's IP address doesn't point back to a machine with a valid email configuration (In the DNs record). Your best solution would be to not bother with the complexities of a mail server, you have no need for one.

If you insist on leaving your computer on 24/7 at a cost of £10 - £15 per month and leaving PN vulnerable to acting as an Open-Relay because of misconfiguration on your part then, they will change your MX (email) DNS entry for you to point to your machine. If any of this is confusing, you don't want that option.
