Configuring Sendmail for the Brightmail
Filter
The Brightmail Client communicates with the Sendmail MTA using the standard
Sendmail Mail Filter API. To implement this integration, the Brightmail Client uses the
Brightmail Filter (
bmifilter
), an intermediary program, which connects to Sendmail
over a socket connection. The Brightmail Filter program also controls client-side actions
such as removing mail and tagging spam. This section tells you how to enable filtering and
the Brightmail Filter in Sendmail. This section includes the following topics:
•
Understanding the Filter Address and Optional Settings
•
Configuring Sendmail Switch to Work with Brightmail Scanner
•
Configuring Sendmail for Brightmail Scanner with sendmail.cf
•
Configuring Sendmail for Brightmail Scanner with M4
Based on the version of Sendmail you are using, do the following:
•
If you are using Sendmail Switch, use the Sendmail Administration Console to define
the filter. See
“Configuring Sendmail Switch to Work with Brightmail Scanner,” on
page 35 .
•
If you are using Sendmail 8.12.11 or later, either manually edit the
sendmail.cf
file,
or if using an m4 file, edit that file. See “Configuring Sendmail for Brightmail
Scanner with sendmail.cf,” on page 40 or “Configuring Sendmail for Brightmail
Scanner with M4,” on page 41 .
NOTE:
During installation, the Brightmail Filter is configured to use port 41001, with a
default setting of
inet:41001
. This Brightmail Filter port number must
correspond to the port number for the
Xbmifilter
setting in Sendmail specified in
this section.
Understanding the Filter Address and Optional Settings
In Sendmail 8.12.11, and later, the
X
setting has the following format:
Xbmifilter,S=inet:port_number@machine.your_domain.com
