[Fail2ban-users] Regex Help (postfix)

[Jacques Lav!gnotte. <ja...@la...>]

Hi list,

Some crazy bot is bugging postfix all day long and filling the logs with
such lines :

Jan 12 11:07:47 emf1pt2-2-35-70 postfix/smtpd[13767]: improper command
pipelining after DATA fromnknown[181.21.131.88]:

Jan 12 11:07:49 emf1pt2-2-35-70 postfix/smtpd[13767]: improper command
pipelining after DATA from unknown[181.21.131.88]:


Despite it looks simple I cant get a working regex.

Can anyone help ?

Thanks,   Jacques
