We have a dedicated server from our ISP - it comes installed with a proprietry email and web server (I think they built it themselves, so there is little tech documentation!). We have been having huge problems with the SMTP server regularly becoming non-responsive.
The techies at the ISP have now informed me that if they disable the JBoss application server (run as a service via JavaService) that they can restart the SMTP service and it works fine. Previously I was having to restart the whole server to get it working.
The techies have informed me that he 'suspects this is due to a conflict between the SMTP server and the virtual SMTP server in JBoss' - I didnt know the application server contained an SMTP server - is this correct? Does JBoss use port 25 for anything internally? I've trawled the conf files but found nothing.
Anybody else seen any sort of conflict like this?

There is no virtual smtp server in jboss. There is no port used below 1024 range.
