If you look in Postfix's source code
./src/util/msg_syslog.c
...
static int syslog_facility;
/* msg_syslog_print - log info to syslog daemon */
static void msg_syslog_print(int level, const char
*text)
{
static int log_level[] = {
LOG_INFO, LOG_WARNING, LOG_ERR, LOG_CRIT, LOG_CRIT,
};
static char *severity_name[] = {
"info", "warning", "error", "fatal", "panic",
};
if (level < 0 || level >= (int) (sizeof(log_level) /
sizeof(log_level[0])))
msg_panic("msg_syslog_print: invalid severity level:
%d", level);
if (level == MSG_INFO) {
--> syslog(syslog_facility | log_level[level], "%.*s",
(int) MSG_SYSLOG_RECLEN, text);
} else {
--> syslog(syslog_facility | log_level[level], "%s:
%.*s",
severity_name[level], (int)
MSG_SYSLOG_RECLEN, text);
}
}
...
that looks to me like Postfix sending pre-assembled string(s) info to
the sys-logger with a format specified.
I can change those strings in Postfix code, recompile, and the output
format that appears in the syslog changes.
Your comment suggests to me that I can instead change that format "in"
syslog.
If that's the case, can you provide an example of how to use syslog
directly to alter that format?
