man smailmeth (Formats) - smail host specific transports configuration

NAME

/etc/smail/methods/ - smail host specific transports configuration

METHOD FILES

Method files define a relation between a set of hostnames and a set of transports to be used in delivering to those hostnames. Method files use the standard routine for reading file entries, just as with the config, directors, routers, and transports files. Each entry should have the form: 

    hostname transport-name
stating that mail being sent to hostname should be delivered using the transport transport-name. As a special case, if the hostname value is the special string ``*'', the entry matches any host. This is a catch-all feature which should only be used in the last entry in a method file.

Entries in a method file can be associated with particular message grades. This allows different grades to use different transports, such as non-demand UUCP for messages with a bulk or junk precedence. Grade ranges are specified by appending a grade letter range to the hostname, separated by a slash (``/''). Entries with grades can be in any of the forms: 

    hostname>/X     transport-name 
    hostname>/X-*   transport-name 
    hostname>/*-Y   transport-name 
    hostname>/X-Y   transport-name
See the definition of the grades configuration variable for a discussion of grade letters, and their correlation with message precedence strings. In the first form, the transport is used for an exact match of the grade letter. In the second form, a match requires a grade a character value of at least X. In the third, form a match requires a grade character value of at most Y. The final form specifies a range of grades from character value X to character value Y.

For example, with the default value for the grades variable, the following file will use smtp for hosts local1 and local2, if the precedence is air-mail or better; otherwise, for any host with a precedence of first-class or better, demand-polled uucp is used; otherwise, queued uucp is used: 

    local1/*-A  smtp 
    local2/*-A  smtp 
    */*-C       demand_uucp 
    *           uucp
