First, determine the MX for the domain in question:
nslookup
set type=mx
mydom.com
should return something like:
Server: ns2.mydom.com
Address: 192.168.1.10
mydom.com preference = 10, mail exchanger = mx.mydom.com
mydom.com nameserver = ns.mydom.com
mx.mydom.com.com internet address = 1.1.1.1
mx2.mydom.com internet address = 1.1.1.2
The last two lines tell you about the mail server (MX = Mail Exchange). In this case, 1.1.1.1 and 1.1.1.2.
So, armed with this knowledge,
telnet 1.1.1.1 25
Server responds with: 220 mx.mydom.com SMTP
HELO
Server responds with: 250 OK
MAIL FROM:user@mydom.com
Server responds with: 250 Address Ok.
RCPT TO:user@otherdom.com
Server responds with: 250 user@otherdom.com OK
DATA
Server Responds (or may not): 354 Enter Mail
Enter message, then on a new line,
.
exit
The message should now be sent. By modifying the MAIL FROM and RCPT TO lines, you can test for open relay.

Ever troubleshoot over the phone? If you've ever done that then you've wished you could copy and paste things back and forth to the person at the other end.
Apparently someone created a site to let you do so. Paste Bin is pure genius as far as I'm concerned. Wish I knew about it sooner.
With the holidays approaching, I give you Elfster, an online tool to organize a secret gift exchange.
It takes care of assigning out the picks and managing wish lists, you can even ask a question anonymously to the person you picked. This should take a lot of the headaches out of this task, if your fellow elves are a bit techo-savy

If you've ever needed disposable email addresses you could both send and receive email from then spamgourmet may be for you. It lets you create an infinite number of disposable email addresses. It requires some setup but does an admirable job.
How it functions is fairly easy. You get assigned a root email username@spamgourmet.com. You can't actually receive email at that though. This is simply the suffix. Now all you need to do is handout and email in the form prefix.number.username@spamgourmet.com. The number is the maximum number of emails you will receive at this address. So if you were buying from amazon.com you could give your email as amazon.5.username@spamgourmet.com. This means you would get maximum 5 emails before it shuts down. There is a whitelisting option that lets you refine the behavior furthere. It has both a simple and expert mode so take a look at both and figure out what you need.
If ever you need an instant email address with zero configuration then the Mailinator is for you. Just put your address as whatever@mailinator.com. Then if you need to check it go to the Mailinator website. Be aware though, no setup equals no password. Everyone can check the mail you get there.
