I'm using Jbuilder4. HTML form collects information from user and mails it using servlet. When I invoke the servlet, it gives me error as follows Error: 500 Location: /servlet/com.TechSupport An error occured while attempting to access the mail server. While my message is my own coded one... I am desperate to run this servlet. Please let me know the easy-to-configure mail server and code changes required. Looking for an earliest reply... Tanveer
