I have a bit of a problem. Spamassassin is set to verbose mode on my box
and is scanning all incoming and outgoing mail. This was achieve by
hashing out the line "return if (defined($ENV{'RELAYCLIENT'}));" in the
qmail-scanner-queue.pl script.
I have a mate that is running the same config as me except he has
Spamassassin set to fast_spamassassin. When his qmail-scanner-queue.pl
script parses the e-mail and removes my spam headers and adds his
headers it breaks the mime types in the e-mail and attachments are no
longer assessable.
I have 2 Qmail processes running. The first excepts connections on port
25 on all interfaces and forwards them to port 26 on 127.0.0.1.
I have 127.0.0.1:allow,RELAYCLIENT="" in my smtp.rules file.
I would like qmail-scaner-queue.pl to only scan incoming messages.
However the line of code: return if (defined($ENV{'RELAYCLIENT'}));
checks for RELAYCLIENTS and obviously 127.0.0.1 is always going to be a
rely client and therefore will not be scanned. How could we overcome
this? Can you do a test to see if the originating IP is in the
RELAYCLIENT list and if so not run spam assassin? i.e. not the last ip
to connect to the script but the originator.
So for example
From an inside client: If I send an e-mail from 192.168.3.130 it will
connect to 193.168.3.1 and then smtproute to 127.0.0.1 on port 26. So
qmail-scanner will go hey this was originally from the internal network
so I'm not going to do the spam check.
From the outside: An e-mail comes in on 203.476.8.xx then gets
smtprouted to 127.0.0.1 on port 26. Qmail-scanner checks the originating
IP address and sees that its from somewhere on the Internet. Then it
decides to check for spam.
The only problem I can see with this is if the originators IP address
range was the same as yours. i.e. if they send it from there internal
network with the same address range!
Let me know if you have any ideas on this.
