<TR bgcolor="#dddddd"><TH>Argument</TH><TH>Description</TH></TR>
<TR valign="top"><TD>oconn</TD>
<TD>The address of the desired communication socket.
The address should be a NULL-terminated string in "proto:address"
format:
<UL>
<LI><CODE>{unix|local}:/path/to/file</CODE> -- A named pipe.
<LI><CODE>inet:port@{hostname|ip-address}</CODE> -- An IPV4 socket.
<LI><CODE>inet6:port@{hostname|ip-address}</CODE> -- An IPV6 socket.
</UL>
</TD></TR>
</TABLE>

<!----------- Return values ---------->
<TR>
<TH valign="top" align=left>RETURN VALUES</TH>
<TD>smfi_setconn will not fail on an invalid address.
The failure will only be detected in <A href="smfi_main.html">smfi_main</A>.
Nevertheless, smfi_setconn may fail for other reasons, e.g.,
due to a lack of memory.

<TH valign="top" align=left>NOTES</TH>
<TD>
<UL>
<LI>If possible, filters should not run as root when communicating
over unix/local domain sockets.
<LI>Unix/local sockets should have their permissions set to
0600 (read/write permission only for the socket's owner) or
0660 (read/write permission for the socket's owner and group)
which is useful if the sendmail RunAsUser option is used.
The permissions for a unix/local domain socket are determined as
usual by <CODE>umask</CODE>, which should be set to 007 or 077.
Note some operating systems (e.g, Solaris) don't use the
permissions of the socket. On those systems, place the socket in a
protected directory.
