USSR Labs found following. A memory leak exists in the Super Mail Transfer Package that may cause an NT host to stop functioning and/or need to be rebooted. The memory leak may occur when you connect to the SMTP port, all information you send to the system will be stored in memory, and SMTP support multiples HELO/ MAIL FROM/ RCPT TO / DATA in the same connection. If you did multiple HELO/ MAIL FROM/ RCPT TO / DATA in the same connection the memory may not be deallocated. This condition may cause the computer to stop functioning the moment memory runs out.
