I have a situation where I'm using an SMTP server that needs some custom properties set on the mail properties (mailProps field in the Spammer class).
For now I've hardwired these additional parameters by modifying Spammer, but it may be worth looking at a more generic way of allowing custom properties to be added to the Spammer. Maybe have a custom file of additional properties or something similar.
If you think that this is a good addition, I'd be glad to do the work and submit a patch for trunk.
Can you give an anonymized example of the properties you would like included?
The easiest way would probably to have a new property in SystemGlobals.properties (something like "mail.smtp.properties"), and to have that made editable on the Configurations page to accept a value like "prop1=value1, prop2=value2".
Cool. There's no need to use svn, apart from the initial checkout. Please open a ticket on SourceForge and attach the patch to that: https://sourceforge.net/p/jforum2/tickets/
