Mimedefang seems to ignore the extra arguments passed by milter.
However, I know you can get at the SIZE= by fetching the sendmail
${msg_size} macro. We're also doing that. You'll need a few steps
to get there:
Put this in sendmail.mc:
dnl # pass extra macros to milter/mimedefang... without repeating
dnl # what cfhead defined `confMILTER_MACROS_ENVFROM' to.
define(`ORIG_confMILTER_MACROS_ENVFROM', confMILTER_MACROS_ENVFROM)
define(`confMILTER_MACROS_ENVFROM',
`ORIG_confMILTER_MACROS_ENVFROM, `{msg_size}'')
(there might be an easier way to add to confMILTER_MACROS_ENVFROM, but
this works too).
Add to the mimedefang command line "-a msg_size" (if you use the standard
shell script, by setting MD_EXTRA="-a msg_size").
Then use something like this:
sub filter_recipient {
#...
read_commands_file();
if ( defined($SendmailMacros{msg_size}) and
$SendmailMacros{msg_size} % 13 == 0 )
{
return('REJECT', 'message size brings bad luck');
}
#...
}
But then by using a slightly more useful test, probably :)
I'm not aware of how to get the ORCPT value. Could be that it's in some
sendmail macro, but I couldn't find it with a quick scan.
