- and relay
(specifically designed for gatewaying messages between hosts).
The uucp transport provides support for two mailers: uucp-old , which is the traditional UUCP, and uucp-new , which allows multiple recipients to be handled in one transfer.
This mailer allows you to send mail messages directly into Usenet style news networks. Any local message directed to an address of news.group.usenet will be fed into the news network for the news.group newsgroup.
If you have the HylaFAX software installed, this mailer will allow you to direct email to it so that you may build an email-fax gateway. This feature is experimental at the time of writing and more information may be obtained from http://www.vix.com/hylafax/ .
There are others, such as the pop , procmail , mail11 , phquery , and cyrus that are useful, but less common. If your curiosity is piqued, you can read about these in the sendmail book or the documentation supplied in the source package.
188.8.131.52. Configure mail routing for local hosts
The Virtual Brewery's configuration is probably more complex than most sites require. Most sites today would use the SMTP transport only and do not have to deal with UUCP at all. In our configuration we've configured a "smart host" that is used to handle all outgoing mail. Since we are using the SMTP transport on our local network we must tell sendmail that it is not to send local mail via the smart host. The LOCAL_NET_CONFIG macro allows you to insert sendmail rules directly into the output sendmail.cf to modify the way that local mail is handled. We'll talk more about rewrite rules later on, but for the moment you should accept that the rule we've supplied in our example specifies that any mail destined for hosts in the vbrew.com domain should be delivered directly to the target hosts using the SMTP mail transport.
