Hi,

   Let's call the mailhost server "A" and the spamd secondary server "B"

   I've done what you said, and I can observ the same kind of error I  
saw before when I was just redirecting the tcp connections.

   Debugging the communications between the 2 servers with ngrep, I  
see *only* traffic from "A" to "B", but no returning traffic from "B"  
to "A". It's not a iptables issue since both servers allow any:any to  
any:any between them for any protocol.

   Things happen like this:

   "A" starts processing of the message until clamd:

Fri, 16 Nov 2007 19:04:24 CET:25833: +++ starting debugging for  
process 25833 (ppid=25830) by uid=89
Fri, 16 Nov 2007 19:04:25 CET:25833: w_c: Total time between DATA  
command and "." was 6.7e-05 secs

x.x.x.x
Fri, 16 Nov 2007 19:04:25 CET:25833: clamdscan: finished scan in 0.023703 secs

   And now:

Fri, 16 Nov 2007 19:04:25 CET:25833: SA: finished scan in 0.021004  
secs - hits=?/?

   At the same second. The funny thing is that "B" receives that  
message, at 19:04:25, scans it, and shows the result of the scan in  
its spamd.log. "A" seems just "throwing" the message to be scanned to  
"B" and exit with a "?/?" status for the spamd part. The short short  
time shown for the spam scan process (0.023703 secs) suggests that  
still there's something missconfigured somewhere.

The original spamc line is:

my $spamc_binary='/usr/local/bin/spamc -t 30';

And the modified one:

my $spamc_binary='/usr/local/bin/spamc -t 30 -d X.X.X.X';

(where X.X.X.X is B's IP)

I'm using the 2.01st version.

Regards,

Ruben.
