by sithlord2 (#48295515) Attached to: Ask Slashdot: How Useful Are DMARC and DKIM?
Basically, there are two sides to implementing SPF and DKIM:

- Outgoing mail: yes, it's probably a good idea to set up SPF and DKIM on your outgoing mail-servers and DNS. You'll less likely end up in the "junk" folder of Hotmail or GMail. Setting up SPF and DKIM is actually not as hard as some people seem to think. There are enough free services on the Internet that will check if your config is correct. While you are at it, make sure your mailserver is configured to use the STARTTLS SMTP command. Most spammers don't use TLS over SMTP, so it's a little extra that can give you an advantage in anti-spam filters.

- Incoming mail: this is where most of the problems arise. There are a lot of mail servers out there that don't implement it, or don't implement correctly. For my personal mail setup (which runs on PostFix), I decided to implement them as they should be (SPF softfail/hardfail according to sender DNS records etc...). If you run a business, this might result in loss of business mail, so might want to ignore SPF and DKIM

TL;DR: Configure it for your outgoing email, ignore it for incoming mail. ("Be Strict with Yourself and Lenient Towards Others" - Fan Chunren )

Sure, but a programming language should not work AGAINST the programmer, and this is exactly what PHP does.

Take a look at this page, and no, it's not an anti-php rant, but an overview of actual facts about PHP:

I made a few PHP projects myself, but since I discovered Python and Django Framework, I would never go back to PHP again.

And why do you assume that the aliens are any better than us?

Q: Why would an alien civilization contact us in the first place?
A: Because they need something from us.

We already know that providing modern technology to civilizations that are not on the same level as us, is not a good idea. Since an alien civilization is more advanced than us (I mean, they are able to visit earth, while we are not capable of visiting other inhabitable planets yet), they already know that too.

So the only reason they would contact us, is if they need something from us, and they need it very badly. And they will probably take it by whatever means necessary.

An alien civilization that contacts us, means big trouble, no matter what...

Do some research about what we did during the colonization of Africa. The same story goes for the discovery of America. We promised them "civilization", promised them better lives, but in the end we just exploited the native population for our own benefits.

If suddenly an alien civilization would show up and make the same promises, we are in deep trouble...

- Implementing DKIM?
- Implementing SPF?
- Make sure the sender address doesn't bounce?
- Make sure you don't open thousands of connections to the receiving party for each recipient ? (in case of yahoo, hotmail, gmail, ...)
- The contents of the e-mail is not considered spam? (provide unsubscibe link, no big images included, etc...)


Setting up a mass-mail infrastructure is not to be taken lightly. There are lots of reasons why you could be listed as a spammer. That's why most companies outsource their their mass-mailing to 3rd parties like MailJet, MailChimp, SendGrid...
