It uses /dev/urandom on
systems that support that device. On systems that don??™t, you must specify an alternative.
The RandFile option is used to specify an alternative source like this:
O RandFile=where ?†? configuration file (V8.11 and later)
-ORandFile=where ?†? command line (V8.11 and later)
define(`confRAND_FILE??,`where??) ?†? mc configuration (V8.11 and later)
Here, where is of type string, and specifies the source for the randomized data. That source
can be either a Unix-domain socket used by the egd(8) daemon (?§5.3.1.2 on page 204), or a
file you update withrandomized data yourself (?§5.3.1.4 on page 204). You tell sendmail
which you are using by prefixing where with either a literal egd: or file: expression:
define(`confRAND_FILE??,`egd:/var/run/entropy??) ?†? socket for the egd daemon
define(`confRAND_FILE??,`file:/etc/randfile??) ?†? a file of random data
See ?§5.3.1.4 on page 204 for a full discussion of how this option and those file types fit into
the STARTTLS scheme.
The RandFile option is not safe. If specified from the command line, it can cause sendmail
to relinquish its special privileges.
