Create a virtual domain, and a virtual user inside that domain
Do a telnet to the port 25 of your server and send a mail to that domain and see if it’s delivered. You can check the error logs through
tail -f /var/log/mail.log -f from a different console. Using telnet is easy

The Heap: This is the memory used to store your objects and is controlled by the -Xms and -Xmx parameters. The Stack: This is the memory used to store the stack frames for the threads that your program maintains and can be controlled with the -Xss parameter. Permgen Memory: This is the memory used to store your compiled classes and pooled strings as well as some other things and can usually be controlled with -XX:MaxPermSize although the -XX represents a debugging parameter, so there's no guarantee it's on all JVM's. But, the default Sun/Oracle reference implementations have always had them. JNI Allocated Memory Any classes utilizing native methods and JNI could potentially allocate unlimited memory. This memory comes from the OS and not the heap and there's no way of knowing how much memory a native class will use without having access to the source. |
