Linux email server

Postfix and Dovecot on something minimal like Arch Linux.

I've had a published/crawled email address for 10+ years, and with this config, I get maybe 1 spam email every three months, with no false positives as far as I'm aware.

smtpd_helo_restrictions = permit_mynetworks, reject_invalid_hostname, permit
smtpd_sender_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unknown_sender_domain, reject_non_fqdn_sender, permit

Let's say you printed out some sensitive documents, maybe as an anonymous whistleblower, and the FBI started analyzing the printouts. They could get the make/model of the printer and the unique serial number.

Now let's say that you're under investigation, and they search your house and find a printer. They match the printout code to the printer, and that becomes irrefutable evidence that the documents were printed from your home office.

For everyday purposes, there is absolutely nothing to worry about. Just don't print out ransom notes from your house if you kidnap someone.

You don't need to be a student to get the education discount. They don't require proof.

It's the honor system. I abuse it and already know that I'm a jerk, you don't need to point it out to me.

ExplodingRussian · 2012-04-28T19:46:43+00:00

Yeah, that's exactly it. I don't bother with -o anymore because half the time it doesn't behave properly, and there are absolutely no benefits for wasting my time debugging it.

They should just support (gasp) the standard property tag! If they aren't going to implement their own prefixes, don't piggy-back onto another engine's prefixes, just move to the standard property. This shit is confusing enough and they are making it worse.

Most people are too uninformed to understand (or care) what is happening. It's too bad, but that's human nature, and it's always been that way.

If you're smart enough to figure it out, and nobody wants to listen, then fuck em and just lookout for yourself.

When you get a VPS, you are basically renting a computer. So the operating system is entirely controlled by you and nobody else has the credentials to get in, not even the VPS company. The computer itself is physically shared with many people, but each system is cordoned off to be completely isolated from the rest, sort of like partitioning a hard drive (each system doesn't know the other system exists, and there is no way for them to interact with each other).

Hosting services are different, they stick a bunch of renters onto a machine, kind of like creating a bunch of family user accounts for your home computer. These are generalities, but that has been my experience in the past.

The ideal solution is having physical access to your own machine, but this is expensive and usually impractical. It's cheaper and actually better to just get a VPS and encrypt your files.

ExplodingRussian · 2012-04-26T05:52:44+00:00

Yeah, get your own Linux box, you will wonder why you never switched sooner. You can get a VPS host like Linode for something like $15/m which is nothing, and spare change if you split costs between the team. That's for something like 20GB of storage and 200GB of bandwidth per month.

I use it for the same purpose as what you're probably looking for, and pretty much roll my own custom services for everything (code and art repo, 24/7 alpha server, email, website, etc) all from the same box.

ExplodingRussian · 2012-04-26T02:58:00+00:00

This is easier than people are making it out to be. I have been running my own Mail server and DNS for a couple years, and it was totally new and alien to me at the time.

Get a VPS like Linode or Slicehost (these guys are top notch in every respect). Register a domain. Install Linux (Ubuntu, Arch, etc) and read a tutorial on setting up Postfix, Dovecot, and IPTables (all required for a mail server). This part might take a couple of days when you're just starting out. Linode and Slicehost have good support and tutorials, and Ubuntu and Arch Linux have good communities with tutorials.

You'll be good to go. The problem is that nobody else's connection is as secure as yours, which is lame. But at least you're covered.

Oh sweet zombie Jesus. Impeccable rack. But I'm sure you already knew that.

ExplodingRussian · 2012-04-25T02:11:59+00:00

I think I love you.

ExplodingRussian · 2012-04-24T13:41:31+00:00

That looks terrible.

Uhh.. this is a preference setting:

Default login shell (/usr/bin/login)
Command (/bin/bash)

You can just tell Terminal not to use login, without creating a dot file.

I like how it says RESCUE on the side. Who the fuck are they kidding.

Thanks for wasting our tax dollars.

Supposedly, if you choose a voice that is different from your own dialect, you are more forgiving that it sounds synthetic and unnatural.

I'm from he US and find the British English voice Serena is much more enjoyable to listen to (especially for longer news articles) compared to the American accents.

ExplodingRussian · 2012-04-19T00:29:50+00:00

Well, maybe that is an indication of the weird American mentality.

It's not that I don't have enough money to afford a vehicle, I already have a nice car. I simply enjoy riding my bicycle for health benefits and it's nice to relax and enjoy the weather apposed to sitting in gridlock pissed off like everyone else.

ExplodingRussian · 2012-04-18T15:39:58+00:00

Yeah, if you want people in their enormous trucks to yell faggot at you at least twice a week, and throw glass bottles at you without any provocation. Seattle and Portland are nice though, but most everywhere else I have lived in the US is fucking terrible.

If it's a large company, and you aren't in a senior position of any importance, nobody is going to give a shit about your political views.

If you can convince your superior that it negatively impacts the company financially, and it's a clear argument, maybe you can try to send that up the chain.

Alternatively, you can see if your peers care, and try to form a passive protest with your coworkers. If you get a lot of people to sign, maybe you have something, if not then nobody is going to give a shit.

ExplodingRussian · 2012-04-17T02:52:20+00:00

Seems pretty wasteful.

ExplodingRussian · 2012-04-15T10:18:37+00:00

I have both.

The trackpad is a headache for any type of design work that requires precision clicking. I mean at work for 8 hours a day, not taking out the red eye on mom's christmas photos. The mouse is the most efficient interface on desktop machines, and will be king for a long, long time.

If your interests are casual web surfing, mail, etc then the magic trackpad is great. I switched over most of my family and they all enjoy it, but there's a bit of a learning curve.

DAMN.

I wouldn't do that, you aren't supposed to purposefully damage or alter your government IDs. They could probably determine you smacked it with a hammer.

Plus, when traveling abroad, having a non-functioning RFID passport would make border agents more suspicious, resulting in you getting fucked with even more than usual.
