Mail Filter

[Rescue9]

I've messed with the code a bit more to make it more friendly for the maildirmake area. I'm actually not sure it works yet as my ISPC3 server is currently on the inside network. I'll hook it up to the outside network tomorrow and test out the code during the day.

Here are the changes I've made to the code:

        function getRule() {

                $content = '';
                $content .= '### BEGIN FILTER_ID:'.$this->id."\n";

                $TargetNoQuotes = $this->dataRecord["target"];
                $TargetQuotes = "\"$TargetNoQuotes\"";

                $TestChDirNoQuotes = '$DEFAULT/.'.$TargetNoQuotes;
                $TestChDirQuotes = "\"$TestChDirNoQuotes\"";

                $MailDirMakeNoQuotes = $TargetQuotes.' $DEFAULT';

                $EchoTargetFinal = $TargetNoQuotes;


                if($this->dataRecord["action"] == 'move') {

                $content .= "
`test -e ".$TestChDirQuotes."`
if ( ".'$RETURNCODE'." != 0 )
{
  `maildirmake -f $MailDirMakeNoQuotes`
  `chmod -R 0700 ".$TestChDirQuotes."`
  `echo \"INBOX.$EchoTargetFinal\" >> ".'$DEFAULT'."/courierimapsubscribed`
}
";
                }

                $content .= "if (/^".$this->dataRecord["source"].":";

Here is the output of the code box:

### BEGIN FILTER_ID:8

`test -e "$DEFAULT/.Yahoo Groups.BGT"`
if ( $RETURNCODE != 0 )
{
  `maildirmake -f "Yahoo Groups.BGT" $DEFAULT`
  `chmod -R 0700 "$DEFAULT/.Yahoo Groups.BGT"`
  `echo "INBOX.Yahoo Groups.BGT" >> $DEFAULT/courierimapsubscribed`
}
if (/^Subject:.*\[backpackgeartest\]/:h)
{
exception {
ID8EndFolder = "$DEFAULT/.Yahoo Groups.BGT/"
to $ID8EndFolder
}
}
### END FILTER_ID:8

Wrapping the code in quotes effectively handles mail folders with spaces. I've also verified that all commands work as written and that the quotes don't break the command.

I'm not quite clear on how maildrop handles the .mailfilter file enough yet, but one of the things that I'm worried about is the 'test -e' line. My understanding of the test cmd is that it doesn't return anything. If this is the case, then the $RETURNCODE variable should always be null. how can you evaluate a null variable.

Maybe the line should read:

`test -e ".$TestChDirQuotes." && exit 1 || exit 0`
if ( ".'$RETURNCODE'." != 1 )

Till or Falko care to comment on this test statement? Am I thinking correctly, or does maildrop interpret this correctly as is?

I'm up and running on the ISPC3 server. I've tested the following code and verify that this works. If the directory doesn't exist, maildrop runs the commands and makes the directory.

`test -e ".$TestChDirQuotes." && exit 1 || exit 0`
if ( ".'$RETURNCODE'." != 1 )

My only problem now is the fact that ALL mail is sent to the first folder in the .mailfilter list. There must be a problem with this code.

if (/^Subject:.*\[backpackgeartest\]/:h)

EDIT: The problem isn't necessarily with the above code. The problem seems to be that when ISPC3 rewrites the rules it doesn't always \ out the brackets. I tried creating rules without brackets and it worked perfectly. However, when I put brackets in there, the first rule in the .mailfilter file didn't have brackets, but the second did. This explains why all the mail is going to the first filter in the list even if it's not supposed to be matching.
