procmail
Synopsis
When
using the procmail
delivery agent, actual delivery
is performed by the procmail(1) program, which
can be used for local delivery. We described one use of
procmail
when we described the
local_procmail
feature (FEATURE(local_procmail)). In that example,
local_procmail
was tuned with LOCAL_
mc configuration macros, but here it is tuned
with PROCMAIL_ mc configuration macros.
Support for the procmail
delivery agent is
included in your mc configuration file like
this:
MAILER(`smtp') ← define first MAILER(`procmail')← define second
Note that the smtp
delivery agent must be defined
before you can define procmail
.
The procmail(1) program can be made to filter
mail and even route mail to different files by changing a few
configuration file rules. For example, it can be used as a delivery
agent to handle inbound bounces for mailing lists by setting up a new
rule in the parse
rule set 0 that routes all
recipients that end in -request
for delivery with
procmail:
LOCAL_CONFIG Kisrequest regex -a@MATCH -request$ LOCAL_RULE_0 R $+ < @ $+ > $: $(isrequest $1 $) $| $1 <@$2> R $* @MATCH $| $+ < @ $+ > $#procmail $@ $3 $: $2 R $* $| $* $2
This bit of magic requires that you first declare a
regex
database-map type (regex) that will match any user part of an address
that ends in -request
. Then we use LOCAL_RULE_0 to
declare three new rules in the parse
rule set 0.
The first tries to match -request
in the address.
The second detects a match and calls the procmail
delivery agent. ...
