[Mimedefang] Filter_relay problem

[Pat Militzer]

Hi, 

I have added a filter_relay that will allow our internal networks to bypass
the filters and just go out. 

Here is the code I used: 

#******************************************************************
# %PROCEDURE: filter_relay
# %ARGUMENTS: hostip,hostname,helo
# %RETURNS:
#  CONTINUE, TEMPFAIL, REJECT, DISCARD, ACCEPT_AND_NO_MORE_FILTERING
# %DESCRIPTION:
# Don't filter for internal machines sending out email.
#******************************************************************
sub filter_relay($$$){
  my ($hostip,$hostname,$helo) = @_;
  my $internal_net1 = "10.100.100";
  my $internal_net2 = "10.100.200";
  $hostip=~  /^(\d+\.\d+\.\d+)./ ;
  my $mailip = $1;
  if($mailip eq $internal_net1 || $mailip eq $internal_net2) {
  		return("ACCEPT_AND_NO_MORE_FILTERING","It's from us it gotta
be good");
  		}
  return("Continue","");
  }

I used the filter_relay from the lisa powerpoint as a template.  That was a
great help in understanding mimedefang.  

It works fine, but I started seeing the following messages in my mail log
file.

The first line is my test mail to see if the filter worked as I thought it
would, and it did but then I saw the filter_relay rejected host
xxx.xxx.xxx.xxx.  I did not set the filter_relay to reject anything, any
idea on what is happening.  Prior to adding the filter I have not seen those
messages or since I took it out? 

I'm using Mimedefang 2.39 with SA, on a Solaris 9 Sparc Box with sendmail. 

Thanks in advance.
