Tailor File

The MTA tailor file (imta_tailor) is an option file in which the location of various MTA components are set. This file must always exist in the msg-svr-base/config directory for the MTA to function properly. The file may be edited to reflect the changes in a particular installation. Some options in the file should not be edited. The MTA should be restarted after making any changes to the file. It is preferable to make the changes while the MTA is down.

An option setting has the form:


The value can be either a string or an integer, depending on the option's requirements. If you make changes to values in order to specify directory paths, note that these values are prefixes, not paths. You must include a trailing slash. Comments are allowed. Any line that begins with an exclamation point is considered to be a comment and is ignored. Blank lines are also ignored. Options that are available and can be edited are shown in Table 4–23.
