There are many ways to crack this problem, though I guess if it is felt neccesary to disable netbios, perhaps for security reasons, most of them would also fall at this hurdle? But then both the feet solution and the email solution are equal, or greater security risks. Or maybe you are dealing with latency and/or bandwidth issues?

If you post a message to this list asking how to start James on boot up in un*x like systems, I'm sure you will get help on how to invoke James' run.sh from a runlevel. We don't have anything recorded for FreeBSD; maybe you can adapt the Linux instructions from the wiki - http://wiki.apache.org/james/RunAsService? > > The James port installation create a shell executabe file in > the rc.d called > 'james', in it there are these lines as a header comment: > > # > # Configuration settings for geronimo%%GERONIMO_VERSION%% in > /etc/rc.conf: > # > # james231_enable (bool): > # Set to "NO" by default. > # Set it to "YES" to enable james231 > # > # > # james231_home (str) > # Set to "/usr/local/james2.3.1" by default. > # Set the JAMES_HOME variable for the James process > # > # james231_base (str) > # Set to "/usr/local/james2.3.1" by default. > # Set the JAMES_BASE variable for the James process > # > # james231_tmpdir (str) > # Set to "/tmp" by default. > # > # geronimo%%GERONIMO_VERSION%%_stop_timeout (num) > # Set to "10" by default. > # Sets the timeout in seconds to allow geronimo to shutdown. > # After the timeout has elapsed, geronimo will be killed. > # > # james231_java_home (str): > # james231_java_vendor (str): > # james231_java_version (str): > # james231_java_os (str): > # Specify the requirements of the Java VM to use.

And embedding is a complicated matter in itself, best avoided unless there is a compelling need. You are best to get James running as you wish in standalone mode before such an adventure. In any event, -mx64m is a very low memory maximum memory limit. A single 30MB message is going to consume almost half of this, so you are asking James core to run in 34MB, which it can't! Try -mx256m and see how you get on. > > The system is a PII (or PIII I do not remember) 460MHz 512MB RAM Antique anyway. With 512MB of RAM and a slooow processor don't expect to run much more than FreeBSD and James if you want to process 30MB messages! > > Cheers > > --Steve > > > many thanks for your help, I work on to try a diffrent > solution and come > back with a feedback if any or not > > c ya > > > > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [email protected] > For additional commands, e-mail: [email protected] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
