Где находятся логи от Postfix и Pure-ftpd?

Пример для postfix'а :

options { 
        chain_hostnames(off); 
        sync(0); 
        stats(43200); 
};

source src  { unix-stream("/dev/log"); internal(); pipe("/proc/kmsg"); };
filter info { level(debug, info, notice); };
filter warn { level(warn); };
filter err  { level(error); };

### Mail ###
destination mailall    { file("/var/log/mail/all"); };
filter      f_mailall  { facility(mail); };
log                    { source(src); destination(mailall); filter(f_mailall); };

destination mailinfo   { file("/var/log/mail/info"); };
filter      f_mailinfo { facility(mail); };
log                    { source(src); destination(mailinfo); filter(f_mailinfo); filter(info); };

destination mailwarn   { file("/var/log/mail/warnings"); };
filter      f_mailwarn { facility(mail); };
log                    { source(src); destination(mailwarn); filter(f_mailwarn); filter(warn); };

destination mailerr    { file("/var/log/mail/errors"); };
filter      f_mailerr  { facility(mail); };
log                    { source(src); destination(mailerr); filter(f_mailerr); filter(err); };

### Other ###
destination mess       { file("/var/log/syslog/messages"); };
filter      f_mess     { level(info..warn); };
log                    { source(src); destination(mess); filter(f_mess); };

destination alert      { file("/var/log/syslog/alerts"); };
filter      f_alert    { level(alert); };
log                    { source(src); destination(alert); filter(f_alert); };

destination emerg      { file("/var/log/syslog/emerg"); };
filter      f_emerg    { level(emerg); };
log                    { source(src); destination(emerg); filter(f_emerg); };
