<h2><a name="compile">Compiling and Installing Your Filter</A></h2>
|
|
|
|
To compile a filter, modify the Makefile provided with the sample program, or:
|
|
<ul>
|
|
<li>Put the include and Sendmail directories in your include path
|
|
(e.g. -I/path/to/include -I/path/to/sendmail).
|
|
|
|
<li>Make sure libmilter.a is in your library path, and link your
|
|
application with it (e.g. "-lmilter").
|
|
|
|
<li>Compile with pthreads, either by using -pthread for gcc, or
|
|
linking with a pthreads support library (-lpthread).
|
|
</ul>
|
|
Your compile command line will look like
|
|
<pre>
|
|
cc -I/path/to/include -I/path/to/sendmail -c myfile.c
|
|
</pre>
|
|
and your linking command line will look something like
|
|
<pre>
|
|
cc -o myfilter [object-files] -L[library-location] -lmilter -pthread
|
|
</pre>
|
|
|
|
<H2><a name="config">Configuring Sendmail</A></H2>
|
|
|
|
First, you must compile sendmail with MILTER defined.
|
|
If you use a sendmail version older than 8.12 please see
|
|
the instructions for your version.
|
|
To do this, add the following lines to your build
|
|
configuration file (devtools/Site/config.site.m4)
|
|
<pre>
|
|
APPENDDEF(`conf_sendmail_ENVDEF', `-DMILTER')
|
|
</pre>
|
|
|
|
then type <code>./Build -c</code> in your sendmail directory.
|
|
|
|
<P>
|
|
Next, you must add the desired filters to your sendmail configuration
|
|
(.mc) file.
|
|
Mail filters have three equates:
|
|
The required <code>S=</code> equate specifies the socket where
|
|
sendmail should look for the filter; The optional <code>F=</code> and
|
|
<code>T=</code> equates specify flags and timeouts, respectively. All
|
|
equates names, equate field names, and flag values are case sensitive.
|
|
|
|
<P>
|
|
The current flags (<code>F=</code>) are:
|
|
<p>
|
|
<table cellspacing="1" cellpadding=4 border=1>
|
|
<tr bgcolor="#dddddd" align=left valign=top>
|
|
<th>Flag</TH> <th align="center">Meaning</TH>
|
|
</TR>
|
|
<tr align="left" valign=top>
|
|
<TD>R</TD> <TD>Reject connection if filter unavailable</TD>
|
|
</TR>
|
|
<tr align="left" valign=top>
|
|
<TD>T</TD> <TD>Temporary fail connection if filter unavailable</TD>
|
|
</TR>
|
|
</TABLE>
|
|
|
|
If a filter is unavailable or unresponsive and no flags have been
|
|
specified, the MTA will continue normal handling of the current
|
|
connection. The MTA will try to contact the filter again on each new
|
|
connection.
|
|
|
|
<P>
|
|
There are three fields inside of the <code>T=</code> equate: S, R, and
|
|
E. Note the separator between each is a ";" (semicolon), as ","
|
|
(comma) already separates equates. The value of each field is a
|
|
decimal number followed by a single letter designating the units ("s"
|
|
for seconds, "m" for minutes). The fields have the following
|
|
meanings:
|
|
<p>
|
|
<TABLE cellspacing="1" cellpadding=4 border=1>
|
|
<TR bgcolor="#dddddd" align=left valign=top>
|
|
<TH>Flag</TH> <TH align="center">Meaning</TH>
|
|
</TR>
|
|
<TR align="left" valign=top>
|
|
<TD>C</TD> <TD>Timeout for connecting to a filter. If set to 0, the
|
|
system's <CODE>connect()</CODE> timeout will be used.
|
|
Default: 5m</TD>
|
|
</TR>
|
|
<TR align="left" valign=top>
|
|
<TD>S</TD> <TD>Timeout for sending information from the MTA to a
|
|
filter. Default: 10s</TD>
|
|
</TR>
|
|
<TR align="left" valign=top>
|
|
<TD>R</TD> <TD>Timeout for reading reply from the filter. Default: 10s</TD>
|
|
</TR>
|
|
<TR align="left" valign=top>
|
|
<TD>E</TD> <TD>Overall timeout between sending end-of-message to
|
|
filter and waiting for the final acknowledgment. Default: 5m</TD>
|
|
</TR>
|
|
</TABLE>
|
|
|
|
<p>
|
|
The following sendmail.mc example specifies three filters. The first
|
|
two rendezvous on Unix-domain sockets in the /var/run directory; the
|
|
third uses an IP socket on port 999.
|
|
<pre>
|
|
INPUT_MAIL_FILTER(`filter1', `S=unix:/var/run/f1.sock, F=R')
|
|
INPUT_MAIL_FILTER(`filter2', `S=unix:/var/run/f2.sock, F=T, T=S:1s;R:1s;E:5m')
|
|
INPUT_MAIL_FILTER(`filter3', `S=inet:999@localhost, T=C:2m')
|
|
|
|
define(`confINPUT_MAIL_FILTERS', `filter2,filter1,filter3')
|
|
<hr width="30%">
|
|
m4 ../m4/cf.m4 myconfig.mc > myconfig.cf
|
|
</pre>
|
|
By default, the filters would be run in the order declared,
|
|
i.e. "filter1, filter2, filter3"; however, since
|
|
<code>confINPUT_MAIL_FILTERS</code> is defined, the filters will be
|
|
run "filter2, filter1, filter3". Also note that a filter can be
|
|
defined without adding it to the input filter list by using
|
|
MAIL_FILTER() instead of INPUT_MAIL_FILTER().
|
|
|
|
<p>
|
|
The above macros will result in the following lines being added to
|
|
your .cf file:
|
|
<PRE>
|
|
Xfilter1, S=unix:/var/run/f1.sock, F=R
|
|
Xfilter2, S=unix:/var/run/f2.sock, F=T, T=S:1s;R:1s;E:5m
|
|
Xfilter3, S=inet:999@localhost, T=C:2m
|
|
|
|
O InputMailFilters=filter2,filter1,filter3
|
|
</PRE>
|
|
<p>
|
|
Finally, the sendmail macros accessible via <a
|
|
href="smfi_getsymval.html">smfi_getsymval</a> can be configured by
|
|
defining the following m4 variables (or cf options):
|
|
<table cellspacing="1" cellpadding=4 border=1>
|
|
<tr bgcolor="#dddddd" align=left valign=top>
|
|
<th align="center">In .mc file</th> <th align="center">In .cf file</TH>
|
|
<th align="center">Default Value</th>
|
|
</tr>
|
|
<tr><td>confMILTER_MACROS_CONNECT</td><td>Milter.macros.connect</td>
|
|
<td><code>j, _, {daemon_name}, {if_name}, {if_addr}</code></td></tr>
|
|
<tr><td>confMILTER_MACROS_HELO</td><td>Milter.macros.helo</td>
|
|
<td><code>{tls_version}, {cipher}, {cipher_bits}, {cert_subject},
|
|
{cert_issuer}</code></td></tr>
|
|
<tr><td>confMILTER_MACROS_ENVFROM</td><td>Milter.macros.envfrom</td>
|
|
<td><code>i, {auth_type}, {auth_authen}, {auth_ssf}, {auth_author},
|
|
{mail_mailer}, {mail_host}, {mail_addr}</code></td></tr>
|
|
<tr><td>confMILTER_MACROS_ENVRCPT</td><td>Milter.macros.envrcpt</td>
|
|
<td><code>{rcpt_mailer}, {rcpt_host}, {rcpt_addr}</code></td></tr>
|
|
</table>
