Note: You can use the accept.txt file in conjunction with this option to make the IMail Server accept the named remote hosts and users as "local" hosts and users. If the host name or User ID is not valid, the server does not relay mail. Select this option from the list box to check the "From" address of incoming mail to determine that it contains a valid IMail Server host name, then checks that host for the user ID. The accept.txt file is only used when the SMTP Relay Setting is set to Relay for Local. You cannot use this option if you are using a "store and forward" setup to relay mail for another server. If a user needs to use an alias for his/her e-mail address, the alias needs to be in the accept.txt file. Select this option from the list box to check the "From" address of incoming mail and verify that it contains a valid IMail Server host name, then checks the host for the user ID. You will still receive mail for local users because a message destined for or originating from the IMail Server host does not use the relay function. Select this option if all of your users send and receive mail from the same host that IMail Server is on, or if they use web messaging to access mail. Selecting this option from the list box enables the SMTP server to refuse to accept mail destined for other hosts (any host not on the IMail Server), unless the user authenticates. The Relay Mail for Addresses page appears. This button is enabled when Relay Mail for Addresses (above) is selected. Likewise, the server will accept mail from other hosts that is destined for specified local addresses. Select this option from the list box to allow the SMTP server to transmit mail originating from local addresses and destined for other hosts. To remedy this, you should choose to Relay Mail for Addresses. Note: If you select this option for mail relay, your server may be blacklisted for running an open relay. Some bulk mailers may take advantage of this capability to not only relay mail through your server, but to make it appear as if mail is originating from your server.
This option is the least secure because it allows your server to be used by anyone to send mail to anyone. Select this option from the list box to allow the SMTP server to accept mail from any host that is destined for any other host, and redeliver that mail (i.e. Select one of the following from the list box: Stop the service, wait 5-10 seconds and restart the service. Important: After making changes, click Save. The following settings and options can be configured to help administer this protocol. Due to its openness, it is difficult to simultaneously block unwanted mail (spam) and keep your mail server available to its users. The SMTP service processes all incoming and outgoing messages. This allows you to Start or Stop individual Services from your respective web pages, as well as from the Service Administration page. Note: At the top of each Services page, the name of the Service, its Status (Running or Stopped), and a Start/Stop button appears. Or Click the Services tab, then click IMail SMTP Server link.Click the Services > SMTP tab, and the SMTP Settings page appears.
