Great Moments in SMTP Conversations

August 18th, 2007 1 comment

Most people online don’t know this unless they’re a support tech. When you send an email your SMTP server actually has a little conversation with the recipient’s mail server. They issue commands back and forth, acknowledge the commands, and process the mail.

Today while looking at a server’s email queue run logs I noticed the following choice bit of server admin humor:

SMTP<< 220 xxxx.xxx.xxx.xxxxx.xx ESMTP spamd IP-based SPAM blocker; Sat Aug 18 08:14:39 2007 SMTP>> EHLO xxxx.xxxxxx.xxx

SMTP<< 250 Hello, spam sender. Pleased to be wasting your time. SMTP>> MAIL FROM xxxxxxx@xxxx.xxxxxxx.xxx

SMTP<< 250 You are about to try to deliver spam. Your time will be spent, for nothing. SMTP>> RCPT TO: xxxxx.xxxxxx@xxxxxxx.xx

SMTP<< 250 This is hurting you more than it is hurting me. SMTP>> DATA

The best part is the server that was receiving the mail (issuing the “hello spammer” responses) intentionally slowed each of its responses down to keep the other server busy. This type of setup actually costs spammers money as a transaction that normally takes under a second is now taking over 3 minutes.

Why I Hate Windows Servers

September 5th, 2006 1 comment

I could go on for pages and pages about why I hate Windows servers, but I realized today that there is one reason that trumps them all:

Every time I pick up a customer issue involving a Windows server that I don’t know how to fix, thinking I’ll learn something and be better off for having done so, it comes back to bite me in the ass and I end up ready to pull my hair out by the time it’s over. No matter how simple an issue it should be, that is always the end result.

So yeah, Windows servers suck.

Big time.

That is all.

Weekend Quickies

July 9th, 2006 1 comment

Happy Sunday everyone. I hope you all had a good weekend and weren’t stuck at work for half of it (like I was).

But hey, I’m not going to argue with time and a half.

Here’s a few links to occupy some time with:

Fellow MarioKartDS owners rejoice! Here’s an explanation and several videos explaining how to dodge blue shells, and here is a video which explains the basics of snaking (or, how to cheat at the game without really cheating).

If you have problems getting your head around the magical workings of DNS (like I do) you should read this article.

Has anyone tried out AcquisitionX for Mac OS X? It’s a P2P app that has a large following, but I never run a new P2P app unless I personally know someone else who can give me a recommendation on it.

Long lost video fun: Randy Johnson reintroduces a bird to its maker with a fastball.

One of the reasons I think Adam Carolla rocks is that he really doesn’t care about the celebrity level of those he is forced to interact with. Case-in-point.

Want a one word, two second summary of the last World Cup 2006 game? Ouch.

Tired of roller coasters? Take a ride on the space shuttle’s booster rocket as it lifts off(quicktime). Link to source/other videos. Be sure to check out the composite separation video.
