Hello

is the following possible and recommended:

- Is it possible to set another passwort for the DB-user (default is  
djigzo/djigzo) and where should it be set?

- Is it possible to down-trim the amount of logging done by Djigzo by  
global setting?

- Is it possible to use the 64Bit OpenJDK JVM?

And BTW is there a rule of thumb for what size of e-mail the default  
of 512MB heap size is sufficient?

Many Thanks

Andreas

Yes that possible. The password can be set in conf/hibernate.cfg.xml  
(see the connection.password setting)

Djigzo uses Log4J. You can change the log levels in  
conf/log4j.properties. If you change for example the root logger to WARN:

log4j.rootLogger=WARN, console

Then only WARN messages will be logged. You can set the log level for  
each individual logger differently. For all available loggers see Djigzo  
Web Admin -\> Logger Manager.

\> - Is it possible to use the 64Bit OpenJDK JVM?

Yes. I personally use the 64bit OpenJDK.

\> And BTW is there a rule of thumb for what size of e-mail the default  
\> of 512MB heap size is sufficient?

Djigzo uses Javamail and Javamail is quiet memory hungry. The amount of  
memory used depends on the number of spool threads. Default number of  
spool threads is 4 (see config.xml).

Kind regards,

Is there any relation between mail size and memory requirement eg.  
something like mail-size \* xxMB \* number-of-spool-threads for the  
sizing or is it merely a performance setting?

Many Thanks
