Zimbra whitelist o blacklist per IP

Picture of Nello

Zimbra whitelist o blacklist per IP: Breve tutorial per mettere in blacklist o whitelist gli IP nella nostra installazione di Zimbra 8.5 o superiore. Utile per DoS e scenari di spam attack

Whitelist

Autentichiamoci come utente zimbra ed editiamo il file

sudo su zimbra
pico /opt/zimbra/conf/postfix_rbl_override

Aggiungiamo nel file /opt/zimbra/conf/postfix_rbl_override i nostri IP, uno per linea con uno spazio ed un OK, esempio:

1.2.3.4 OK
1.3.4.5 OK

Ora eseguiamo i seguenti comandi

postmap /opt/zimbra/conf/postfix_rbl_override
zmprov mcf +zimbraMtaRestriction 'check_client_access lmdb:/opt/zimbra/conf/postfix_rbl_override'

ATTENZIONE: Il comando postmap deve essere eseguito ogni volta che viene aggiunto o rimosso un IP dal file postfix_rbl_override.

Blacklist

Autentichiamoci come utente zimbra ed editiamo il file

sudo su zimbra
pico /opt/zimbra/conf/postfix_blacklist

Aggiungiamo nel file /opt/zimbra/conf/postfix_blacklist i nostri IP, uno per linea con uno spazio ed un REJECT, esempio:

1.2.3.4 OK
1.3.4.5 OK

Ora eseguiamo i seguenti comandi

postmap /opt/zimbra/conf/postfix_blacklist
zmprov mcf +zimbraMtaRestriction 'check_client_access lmdb:/opt/zimbra/conf/postfix_blacklist'

ATTENZIONE: Il comando postmap deve essere eseguito ogni volta che viene aggiunto o rimosso un IP dal file postfix_blacklist
