3301 | The name of the configuration file is taken from a list that is included in the | |
3302 | binary of Exim. It can be altered from the command line, but if that is done, | |
3303 | root privilege is immediately withdrawn unless the caller is root or exim. | |
3304 | The first file on the list that exists is used. | |
3305 | ||
3306 | For use on multiple systems that share file systems, first look for a | |
3307 | configuration file whose name has the current node name on the end. If that is | |
3308 | not found, try the generic name. For really contorted configurations, that run | |
3309 | multiple Exims with different uid settings, first try adding the effective uid | |
3310 | before the node name. These complications are going to waste resources on most | |
3311 | systems. Therefore they are available only when requested by compile-time | |
3312 | options. */ | |
