Re: [Servers] Email Server at home You have a couple of points to consider here. You said that you have a cable connection. Have you verified that port 25 is not blocked in either direction, ie. inbound and outbound? Most residential cable providers block inbound port 25 (which means you're out of luck), and many are now also blocking outbound as well.
As for your second question, what you are looking for is someone who will add your domain to their mail server and spool mail for you while your server is down. You would add their mail server as a secondary MX record, like this.
mydomain.com IN MX 10 mymailserver.mydomain.com.
mydomain.com IN MX 20 backupmx.somemailprovider.com.
The numbers in those records are preference. Mail servers will send to the server with the lowest preference first. If that server is unreachable, it will then try the next lowest preference. To learn more about this, search for "mail spooling" and "secondary mx". It's considered an old school service these days, though, so you might not to easily find someone who will do it for you cheaply. It can be quite the headache for mail admins. |
