You know, I'm a horrible, horrible geek. I'm just not happy unless I have my fingers dirty, my sleeves rolled up and my hands in some sort of project -- it doesn't matter if that project is a car engine rebuild, a computer overhaul, pulling single-mode fiber or something else, I feel compelled to keep myself busy. Tonight's project of choice is Sendmail, and overhauling it so that I can allow people to relay their SMTP traffic through me without becomming some spammer's bitch. I was able to locate a couple documents and followed them closely. It seemed like everything worked just fine! There's just... one.... teensy little problem: I can't for the life of me figure out why it isn't actually working. I turned on AUTH, I turned on STARTTLS, I got all my certificates in a row, AUTH PLAIN shows up as an extended option...

... and the damn thing still won't let me relay. When I base-64 encode my username and password I get a string that looks okay. I get a challenge that looks okay. I pass it to the Sendmail connection with the proper syntax (the syntax looks okay too)... and whammo, failure.

# telnet localhost 25

All I get from /var/log/maillog is

I just don't get it. Ah well. It's not terribly important, but it would be nice to get SMTP AUTH working for relays so that I can stop opening up my server to half of Southern Minnesota, ya know?

In other news I went to another real estate agent today (one who happens to be local to my complex no less), and asked her to list options for me in the Wheeling/Buffalo Grove/Vernon Hills area. I wasn't terribly surprised when the answer was "townhouse, condo or coach home?" I'm not enthused about any of those choices -- I've spent the last seven years sharing walls with other people, I would like it to stop now please. I guess this means I'm back to looking at Lansing... but I'll continue to have this agent research options for me in the Northwest Suburbs to see what I might find. You never know, I might like a townhouse. While I seriously doubt it would ever happen (lightning is more likely to strike first) I can't know for certain if I don't at least look.

The epic search continues!

I woke up this morning with a buzz rolling 'round in my brain
