Подправил конфиг, ip банятся а сообщение на почту не идёт , в чём касяк ?  
# "ignoreip" can be an IP address, a CIDR mask or a DNS host

# "backend" specifies the backend used to get files modification. Available
# options are "gamin", "polling" and "auto".
# yoh: For some reason Debian shipped python-gamin didn't work as expected
#      This issue left ToDo, so polling is default backend for now

# Default banning action (e.g. iptables, iptables-new,

• fail2ban не шлёт письма о бане postfix ,dr7534, 13:29 , 13-Окт-11

Аууу народ неужели никто не сталкивался с этой проблемой ?

*************************** и еще ********************* люди внимательно повторяю внимательно читаем конфиги

# Action shortcuts. To be used to define action parameter

# Choose default action.  To change, just override value of 'action' with the

объясняю для таких жешь как и я, по умолчанию fail2ban ничего и никому не шлёт ! А вот если указать не action = %(action_)s ,а action = %(action_mwl)s или action = %(action_mw)s то горячё желаемое свалится нам на ящик
