A new spam strategy for me

September 27th, 2006

I get a lot of email. Mountains of the stuff. A fair chunk of it spam. A consequence of having some older email addresses that still forward mail to me. As a result I spend quite a bit of time perfecting spam defenses. I used amavisd-new, dspam, grey-listing, SpamAssassin, SPF, DK/DKIM, p0f, bogofilter and Anomy and anti-virus all mingled together and tuned to an inch of their lives. My mail server burns some serious memory and CPU and has the world’s most damned complicated Postfix configuration. Recently, however, I threw my hands in the air and said “Enough!” Another approach was needed.

So I started doing some investigation and discovered qpmstpd – which a very fast SMTP proxy written in Perl that comes with plug-ins for a variety of purposes – again all written in Perl. It sits in front of my Postfix and processes mail for spam and then submits it to the queue. After some initial tweaking it worked perfectly and the resulting configuration has greatly – greatly – simplified my mail configuration. The reduction in Postfix complexity alone (I nearly needed a flowchart to work out where mail was routed and injected) makes life considerably easier. The simplified anti-spam configuration in qpsmtpd also much easier to manage.

Initial testing also reveals only a slight increase in spam slipping through and that’ll reduce as I tune SpamAssassin with some more training. Performance also much improved and my box isn’t sucking up anywhere near as much memory and CPU – which might prolong the lifespan of the box.

I did need to add a new plug-in to do SMTP authentication for qpsmtpd. Luckily I found an older, not functional, plug-in that I adapted and fixed. You can find the updated auth_smtpd plug-in at the qpsmtpd wiki. Enjoy.

Singing True Blue with a Polish taxi driver – interlude with cabbage roll

September 20th, 2006

I was sick this morning so I called a cab to go across to my place to pick up some things (minding the old’s house for a few weeks *sigh*).

The cab arrived and the driver waves at me from across the street. I walk across and open the door. Instantly the strong smell of cabbage wafts out at me.

“Hello! I am Vlad – good morning to you!”

The driver, a huge bearded fellow, with a thick Eastern European accent extends his hand to me. I shake it as I am clamber into the taxi.

“Where do you go this morning?” he booms at me.

“Um … Smith St, Collingwood,” I reply, a little subdued at his vigour this early in the morning.

“Excellent – we go!” he booms again.

I notice the between us a plastic bag with a large tupperware container in it. The container seems to hold long cigar-like objects, only coloured a greeny-white. Vlad notices me looking.

“You like cabbage? My wife make best cabbage roll in Australia!” He laughs like this an excellent joke – we Australians are obviously not noted for our cabbage rolls. I suspect he right.

“You have one!” he gestures at the container.

“Umm… Okay. As long as you don’t mind. I am not stealing your breakfast am I?” I ask.

“No! No! Take one – take two. Wife will be pleased if I tell her passenger like her cabbage rolls,” he half-shouts at me, a huge smile his face. He yanks open the container whilst performing a deft one-handed U-turn and nearly clipping my father’s car. I wince. I also suspect I better like the rolls.

I carefully pull a roll from the box and take a bite. It’s good. Rice, beef and little pieces of onion.

“Wait, wait,” he says me to, “I have sauce. Tomato. Like for BBQ but better!” He pushes the plastic bag further open and hauls out a smaller, rounder container filled with a reddish liquid. At no time do his eyes actually drift toward the road and I pray we don’t collect something or worse someone. I open the container as it passed to me and dip the un-bitten end of the roll into it. It tastes even better with the sauce. And it considerably nicer than the tomato sauce we slather sausages and steak at BBQs.

“You like?”

“Yeah, it’s great,” I reply munching quickly.

I ask the inevitable question, “So, where are you from?”

He grins at me, “Poland.”

I speak without thinking, “I didn’t think Vlad was a Polish name … more Russian?” Shit, shit, shit. I don’t know how the Poles feel about the Russians but I am assuming like much of the former Iron Curtain states it won’t be good.

He seems unfazed. “Yes – Russian name with V – Polish name with W. I am Wlodzislaw. But no one except Polish people can say, so I am Vlad to everyone.”

I try the full name out a couple of times. He corrects me once.

“Yes, you have right – perfect.”

We drive , him talking non-stop about Australia and Poland.

“Many Polish people here, too bloody cold in Poland. My wife much prefer weather here.” The ‘bloody’ comes out sharply emphasized in that way much Australian slang does when used by people who speak English as a second language.

Both our eyes follow the walk of an attractive woman in a skirt with the side split crossing Spencer St. “I prefer weather here too,” he looks and me and laughs when he sees we have being admiring the same woman.

“You like music?” he asks.

“Yes.” That seems a safe answer.

“Well I love Australian music. I listen to all the time. You mind?”

“No, not at all.”

He leans over and pushes a CD into the player. After a few seconds out blares, John Williamson’s “True Blue”. I wince.

Hey True Blue, don’t say you’re gone.
Say you’ve knocked off for a smoko
and you’ll be back later .
Hey True Blue Hey True Blue.

“You like?”

“Um, yes I guess. I don’t like much country music.”

“They play this at Steve Irwin’s funeral so I put in car this morning. I play for all passengers this morning.” And then he started singing along. After a couple of lines he looked at me, “Come , you sing too!”

So I did and we rolled up Victoria Parade loudly singing True Blue – his booming voice and my scratchy throated rasp.

He dropped me outside my house. I paid him and thanked him for the cabbage roll.

“No worries mate!” he boomed back and drove away.

Only in .

On the road to another White Australia Policy?

September 18th, 2006

Shucks who knew politicians from both parties missed the White Australia Policy*? First Bomber Beazley’s comments suggesting visitors to Australia sign an ‘oath’ to abide by Australian values (oh yes – that’ll stop terrorism – “Damn can’t attack Australia now – they’ve made me sign this ‘oath’ saying I’ll be everyone’s mate. Crikey…”). Now shining light for tolerance Andrew Robb wants to change immigration laws to extend the time required to convert permenant residency to citizenship and administer a language test before conferring citizenship. A slippery slope perhaps? Are we heading back to the dark days of the White Australia Policy and eroding the good works of the Whitlam and Fraser governments in reforming Australia’s previously shameful immigration policy? As Barton did in 1901 at the start of the White Australia Policy, the current government acknowledges that this change in immigration laws an act of appeasement rather than likely to have any substantial impact the quality of our citizens.

Against abortion? Don’t have one.

September 17th, 2006

Yesterday, our way to R’s parent’s auction, we passed a small’ish group of Christian crazies marching through Collins St to protest against abortion. R and I both glared at them briefly and then went back to our papers. They had laminated matching signs and charming pink balloons. Overall I was under-awed. R wanted a pen to write a slogan her newspaper to show them out the window of the tram. We refrained but both concurred the wording:

Against abortion? Don’t have one.

Hopefully most of those mindless bigots will get increasingly marginalised – whilst many aspects of our society seem to be drifting toward conversativism I think abortion one of those issues that unites a lot of women both sides of politics. Now if a few more men (Hi Tony!) – who have zero stake in the issue of a women’s control over her own body – would get the message then we’d be set.

Why I’d make a lousy believer but a great fundamentalist

September 12th, 2006

I’d be a lousy Christian or a Muslim. Firstly, there the ‘not believing in God’ part. That generally puts paid to most religions. Secondly, I don’t like the turning the other cheek, treating others as you’d like yourself to be treated, all that being nice to God’s creatures yadda yadda yadda. Also none too keen humility, charity … let alone chastity, poverty and obedience. But I was thinking I’d make a great fundamentalist. I am arrogant, egotistical, unable to admit when I am wrong, and often derogatory about other people’s ideas. I’d be perfect as a Christian or Muslim fundamentalist. Of course, it’s all moot because of that little ‘not believing in God’ part. It’s a shame because I think it’s a great loss to fundamentalism.

Nancy of the Overflow

September 7th, 2006

Nancy of the Overflow , as you would expect, a homage of sorts to the classic Clancy of the Overflow by Banjo Paterson. Very enjoyable.
