Helpful Service Machines

Mail Relay

Since a leased line account is assumed to be connected all the time, Internet mail is sent directly to these accounts through the customer's mail servers.

Outgoing mail is usually handled by the site's mail server. However, some sites who cannot send out mail directly use one of our Mail Relay machines. If your site uses one of our Mail Relay machines, make sure you use the fully qualified domain name.

It will randomly use one of three machines. If one of the three machines goes down for any reason, mail is seamlessly handled by the others.

Backup Mail Exchangers

If your site loses connectivity, your mail will be sent to one of the Backup Mail Exchangers. Once your site regains connectivity, your mail will be downloaded to your mail server.

You should check to see that these backup mail exchanger records are in place for your site. If you have nslookup, you can check for your mx records with the following commands:

	nslookup
	set q=mx
	domain_name.com

In addition to your MX record, there should also be a record for a mail server that is not on your site's network, a backup mail exchanger.

If your site does not have backup mail exchangers listed, you can e-mail our Hostinfo group to have one of ours listed for your site at no extra charge.
