5.4.2. Content filtering in MTA Sendmail
The nod32smfi serves as a content filter for MTA Sendmail. It is a third-party program that
accesses all the mail messages being processed by MTA Sendmail and therefore can be used in
the bidirectional scanning scenario.
In order to enable filtering, please provide the following line in the section [smfi] of the config-
uration file: /etc/nod32/nod32.cfg set:
accesses all the mail messages being processed by MTA Sendmail and therefore can be used in
the bidirectional scanning scenario.
In order to enable filtering, please provide the following line in the section [smfi] of the config-
uration file: /etc/nod32/nod32.cfg set:
smfi_sock_path = "/var/run/nod32smfi.sock"
With these settings nod32smfi will communicate with the MTA Sendmail via unix socket
/var/run/nod32smfi.sock.
In the next step, modify the /etc/mail/sendmail.cf file by adding the following specification
into the section MAIL FILTER DEFINITIONS:
/var/run/nod32smfi.sock.
In the next step, modify the /etc/mail/sendmail.cf file by adding the following specification
into the section MAIL FILTER DEFINITIONS:
Xnod32smfi, S=local:/var/run/nod32smfi.sock, F=T, T=S:2m;R:2m;E:5m
