How to make friends with my mail filters

Don’t send from hotmail if you can help it. I don’t know why my spam filter thought the header was forged (for all I know it was perfectly genuine) but I suspect (some of?) the hotmail gateways assign random IP addresses, without having an actual host with that address.

Also have an address without numbers if at all possible. The “likely spammer email” mentioned below was of the type “name2006”. This only got 0.4 points, but it was the straw that broke the camel’s back.

If you can’t help sending from hotmail (for instance, as in this case, because your message is the change-of-address from hotmail to something else…) try to make it send plain text. My antispam software is very suspicious of HTML. I’ve already deleted my own filters that throw away all HTML to get rid of some of the false positives, but SpamAssassin is diligent.

I don’t know the reason for the 40% to 60% Bayesian spam probability. Perhaps because there was very little text, only “Hi, my old address is X, my new address is Y, thanks”. But that didn’t give any points, so never mind.

Content analysis details: (5.4 points, 5.0 required)

2.0 HTML_MESSAGE BODY: HTML included in message
0.0 BAYES_50 BODY: Bayesian spam probability is 40 to 60%
[score: 0.5070]

I did catch this one, but I can’t guarantee that I always will. I have SpamAssassin and the filters to avoid having to see every single message that comes in.

Dear spammers.

I don’t want to buy software, not even at reduced price. I don’t use Windows. I use Linux; there’s no need for me to buy software.

Not being in the possession of a penis, a dick or a cock, I’m not interested in ways to enlarge it. Nor am I interested in ways to make or keep it as hard as a rock. Quite apart from the question whether that would be painful. Oh, and SS. Peter and Paul aren’t interested either, thank you very much.

Also, I’m not a customer of the Bank of America, or of any other bank in America. And if my own bank has anything to tell me, they do it by snail-mail and spell my name right.

And I’m against gambling on principle. There’s no need to offer me bigger and bigger bonuses in your online casinos.

Last but not least, the real-world pharmacy I use serves all my needs and I don’t need an online one in Canada.

Spam can be fun

Having been without a computer for two weeks, I had to catch up on mailing-list management. Four mailing lists; two messages on one list from someone who forgot to subscribe with his other address before posting; all the rest, about two hundred held messages in all, were spam. Ninety-nine percent of the spam in my personal mailbox is spirited away by my various anti-spam tools, so I don’t see the really interesting subject lines, such as these:

We’ve students from all works of life. Apparently, they’re not very advanced students yet, or English isn’t what they’re studying.

Your academic qualification expired. Even if I had one, how can it expire? And even if it can, how would they know?

Please upgrade

I love the pieces of spam I keep getting that tell me to upgrade my mail software. Sometimes they’re blunt to the point of rudeness (“Get a better mailer.”), but today I got, not for the first time, one that was actually polite:

Your Email Client does not support MIME encoding. Please upgrade to MIME-enabled Email Client (almost every modern Email Client is MIME-capable).

In fact, my Email Client does support MIME encoding (it’s KMail). It’s just that I’ve turned it off.

That’s not us!

Five mail messages in one day, spread over three accounts, purporting to come from the Valdyas.org team and warning me that I was spreading spam and viruses, that I’d probably caught a trojan, and to use their free anti-virus tool or configure their free forwarding service.

That can’t be from us. For one thing, the Valdyas.org team is Boudewijn and me, and we never sent it. There is no such thing as “support@calcifer.valdyas.org”. If I had a virus (which seems unlikely on my Linux-only computer) the sysadmin, that is, my husband, would tell me, not send impersonal messages to each one of my accounts.

Afterthought

Orthodox Christians should write and paint and sing and dance. We should make movies and television shows. We should make clothes and produce textiles as art as well (the fullness of culture is itself too large to describe in a sentence, a paragraph or even a book). And in all these activities, they will be expressive of the fullness of our humanity without having to stick an icon on everything to prove its Orthodoxy.

—Father Stephen in Glory to God for All Things
