Hello,
I have found our latest problem - we have a mail loop! Here's the command
used to send the mail back to exim once it's been checked (I think):
/usr/sbin/exim4 -oMr spam-scanned -bS
And here are the router and transport in full, which I am using:
THE ROUTER:
# spamassassin stuff
sa_router:
no_verify
check_local_user
# When to scan a message :
# - it isn't already flagged as spam from Spamassassin
# - it isn't already scanned
# - it isn't local
# - it isn't from one internal domain user to another
condition = "${if and { \
{!def:h_X-Spam-Flag:} \
{!eq {$received_protocol}{spam-scanned}} \
{!eq {$received_protocol}{local}} \
{!eq {$sender_address_domain}{$domain}} \
} \
{1}{0}}"
driver = accept
transport = sa_spamcheck
local_parts = /etc/spamassassinUsers
# end of spamassassin stuff
THE TRANSPORT:
# spamassassin stuff
sa_spamcheck:
driver = pipe
command = /usr/sbin/exim4 -oMr spam-scanned -bS
use_bsmtp = true
transport_filter = /usr/bin/spamc
home_directory = "/tmp"
current_directory = "/tmp"
user = spamcheck
group = spamcheck
log_output = true
return_fail_output = true
return_path_add = false
message_prefix =
message_suffix =
# end of spamassassin stuff
Also, we are using exim-daemon-light as our MTA.
Any ideas??
Thanks in advance,
Richard.
Is "spamcheck" a trusted user? If not it won't be able to set the protocol
on the exim command.
Also, I would not skip checking if the X-Spam-Flag header is present. That
means all the spammer has to do is insert this header and your spam checking
will be bypassed completely.
