You made a typo in the config file, which made fail2ban fail on an
earlier restart. The logrotate just tripped over the fact that f2b
wasn't running some days later.
Please show us your jail and filter config for the postfix-disc jail,
but my first guess would be that you setup the jail using
logfile=%(syslog_mail)s
but the variable 'syslog_mail' is not defined anywhere.
Kind regards,
