s problem is called DNS servers(17).11. Finding out what your ISP's mail servers are - there are several ways to do this:1) Call your ISP and ask them what is the IP address(9) or the hostname(10) of your outgoing mail server (this is the IP/hostname you will need to perform all the tricks in this tutorial). If you want to know a different ISP's mail server, call their tech support phone number. But what if they're on the other side of the world and you don't feel like spending tons of cash simply for calling them and being put on hold? In this case, try method 3.2) Start up your mail client, go to your preferences page and find what it says in the 'outgoing mail' field or in the 'SMTP server' field (both are the same. SMTP stands for Simple Mail Transfer Protocl, which is a protocol(18) that is used to send Emails over the Internet).3) Guessing. If your target server is someone.com, their mail server should either be mailgw.someone.com:25 (mailgw.someone.com on port(2) 25. Note: mailgw stands for mail gateway) or someone.com:25. If not, send an Email to admin@someone.com or support@someone.com and ask them what their mail server is (they should be happy to answer you, unless you tell them that you're an evil hacker or something. In that case they'll call the cops on you).Note: not every server on the planet has an outgoing mail server.12. Portscanner - a program that scans a target for open ports(2) by trying to connect to it on various ports. The simplest portscanner will start at port 1 and climbs up, but you can tell more advanced portscanners to scan a specific range, give you some info on open ports it might find etc'.13. Services scanner - a services scanner is much more sophisticated than a portscanner(12) since it tries to connect on predefined ports which should have the service(3) you're looking for on them.14. Root - an account on Unix computers which has maximum priviledges (read any file, write (and delete) to any file, ex...
