This command shows details about exim.
This option causes Exim to write the current version number, compilation number, and compilation date of the exim binary to the standard output. It also lists the DBM library this is being used, the optional modules (such as specific lookup types), the drivers that are included in the binary, and the name of the run time configuration file that is in use.
As part of its operation, -bV causes Exim to read and syntax check its configuration file. However, this is a static check only. It cannot check values that are to be expanded. For example, although a misspelt ACL verb is detected, an error in the verbâs arguments is not. You cannot rely on -bV alone to discover (for example) all the typos in the configuration; some realistic testing is needed. The -bh and -N options provide more dynamic testing facilities.
