My boss in our northern office literally told my colleague that he'd been refreshing the site several times every few minutes and could clearly see that we hadn't done shit.

Keep in mind that we are heavily cached with Varnish and Drupal Cache on our server, and this guy is never at the office. He was seeing our website from 3 days ago because his browser was retrieving local cache from the last time he was actually there and it was during a time where we had some broken items on the site.

The part that pisses me off most is that not only did he not know to purge his browser cache to see changes, but he thought my coworker was making up hocus-pocus technobabble to "cover for me" by telling him how to clear his cache.

This guy installed AirMail, 8 times on his Mac because he was entering SMTP settings that were literally given to him in screenshots with every step illustrated and every field of configuration available for reference, incorrectly. So yeah I can see how he would be technically capable of micro managing me. Fuck.

I absolutely love the email protocols.

IMAP:
x1 LOGIN user@domain password
x2 LIST "" "*"
x3 SELECT Inbox
x4 LOGOUT

Because a state machine is clearly too hard to implement in server software, clients must instead do the state machine thing and therefore it must be in the IMAP protocol.

SMTP:
I should be careful with this one since there's already more than enough spam on the interwebs, and it's a good thing that the "developers" of these email bombers don't know jack shit about the protocol. But suffice it to say that much like on a real letter, you have an envelope and a letter inside. You know these envelopes with a transparent window so you can print the address information on the letter? Or the "regular" envelopes where you write it on the envelope itself?
Yeah not with SMTP. Both your envelope and your letter have them, and they can be different. That's why you can have an email in your inbox that seemingly came from yourself. The mail server only checks for the envelope headers, and as long as everything checks out domain-wise and such, it will be accepted. Then the mail client checks the headers in the letter itself, the data field as far as the mail server is concerned (and it doesn't look at it). Can be something else, can be nothing at all. Emails can even be sent in the future or the past.

Postfix' main.cf:
You have this property "mynetworks" in /etc/postfix/main.cf where you'd imagine you put your own networks in, right? I dunno, to let Postfix discover what your networks are.. like it says on the tin? Haha, nope. This is a property that defines which networks are allowed no authentication at all to the mail server, and that is exactly what makes an open relay an open relay. If any one of the addresses in your networks (such as a gateway, every network has one) is also where your SMTP traffic flows into the mail server from, congrats the whole internet can now send through your mail server without authentication. And all because it was part of "your networks".

Yeah when it comes to naming things, the protocol designers sure have room for improvement... And fuck email.

Oh, bonus one - STARTTLS:
So SMTP has this thing called STARTTLS where you can.. unlike mynetworks, actually starts a TLS connection like it says on the tin. The problem is that almost every mail server uses self-signed certificates so they're basically meaningless. You don't have a chain of trust. Also not everyone supports it *cough* government *cough*, so if you want to send email to those servers, your TLS policy must be opportunistic, not enforced. And as an icing on the cake, if anything is wrong with the TLS connection (such as an MITM attack), the protocol will actively downgrade to plain. I dunno.. isn't that exactly what the MITM attacker wants? Yeah, great design right there. Are the designers of the email protocols fucking retarded?

So we hired an intern and his first task was to change a few things in email layout for our client, which is an investment bank.

I told to one of my developers to make his local database dump and setup the project for an intern. When intern completed the task, my developer thought that title "Dow Jones index crashed" was pretty funny title for a test.

What he didn't thought through enough, is that he forgot to configure fake SMTP server and he had production database dump with real email addresses.

I had really awkward 20 minutes conversation with our client. Fuck my life.

And again...

Our ISP doesn’t say it blocks any port on our Business Fixed IP. Currently I’m trying to access port 25 for SMTP. Guess what? Indeed port blocked. Called them “The port is open”, I visit a port checked, the same thing “Port Closed”

Always the fucking same thing. Every fcking time. These are just criminals. Lastly I removed their router, that they mentions was the only working router in our house and our signal from the other router, not provided by them was much better. They blocked the hotspots because we removed the router then. Guess what? On their site is an option Enable Hotspot on your home router (this enables your access to hotspots). Just pressed it. Haaa they can’t acces my router to set that up and it works.

In our second home, we have another ISP, Proximus, first they did difficult to come and install everything. Because in the appartment the previous owners didn’t pay the bills. After a week or so someone came to install it. Because they cut the cables couldn’t do it myself. Ok it worked for some time. After 3-4 months by once I can’t access the camera there, strange. My uncle went there and there was no internet. Neither TV. But we never received any invoice. Because they didn’t send them. We contacted them, no response. My father sends them an email, with politic people in copy and by once they called to say they will turn it back and scrap the invoices that were not send. They said no technician needed to come, as it’s second home. Guess what, next day a message came “We will arrive in less than an hour”
My uncle went. They did nothing, only restart the modem.
There still was no internet after two days after they came. We called back, response was: “There wasn’t anyone.” Yeah right, we have proof of a technicial that passed (Local Video). By once the internet worked.
Now 4 months later, still didn’t receive any invoice, neither via post or email.

Fuck those criminals, called ISPs

I used to be a sysadmin and to some extent I still am. But I absolutely fucking hated the software I had to work with, despite server software having a focus on stability and rigid testing instead of new features *cough* bugs.

After ranting about the "do I really have to do everything myself?!" for long enough, I went ahead and did it. Problem is, the list of stuff to do is years upon years long. Off the top of my head, there's this Android application called DAVx5. It's a CalDAV / CardDAV client. Both of those are extensions to WebDAV which in turn is an extension of HTTP. Should be simple enough. Should be! I paid for that godforsaken piece of software, but don't you dare to delete a calendar entry. Don't you dare to update it in one place and expect it to push that change to another device. And despite "server errors" (the client is fucked, face it you piece of trash app!), just keep on trying, trying and trying some more. Error handling be damned! Notifications be damned! One week that piece of shit lasted for, on 2 Android phones. The Radicale server, that's still running. Both phones however are now out of sync and both of them are complaining about "400 I fucked up my request".

Now that is just a simple example. CalDAV and CardDAV are not complicated protocols. In fact you'd be surprised how easy most protocols are. SMTP email? That's 4 commands and spammers still fuck it up. HTTP GET? That's just 1 command. You may have to do it a few times over to request all the JavaScript shit, but still. None of this is hard. Why do people still keep fucking it up? Is reading a fucking RFC when you're implementing a goddamn protocol so damn hard? Correctness be damned, just like the memory? If you're one of those people, kill yourself.

So yeah. I started writing my own implementations out of pure spite. Because I hated the industry so fucking much. And surprisingly, my software does tend to be lightweight and usually reasonably stable. I wonder why! Maybe it's because I care. Maybe people should care more often about their trade, rather than those filthy 6 figures. There's a reason why you're being paid that much. Writing a steaming pile of dogshit shouldn't be one of them.

I installed sendgrid on my server today for the first time. Now I have several questions to you more experienced programmers.

1. Is there anything I should know about using sendgrid for server generated mails?

2. Can I still use my own configured Mail-Server (eg. for sending emails with Thunderbird?

3. How does sendgrid work?

4. Are there probably better alternatives? (I first wanted to use mailgun, but those fuckers want me to have a credit card for registration)

I fucking hate web development and fuckton of issues it has. Laravel library not found despite the files exists and composer loaded it in the autoloader, fix: create a config file for the lib, why? Because magic. The code cannot find the provider class without it....
Next, try out smtp mail. Works everywhere, but not with the live smtp server. Fails with Invalid recipients error. 2 hours later, with half of my hair torn out I finally figured out. Can you guess?
Credentials and settings are correct, recipients are also correct. The fucking from address parameter was the culprit because you cannot send emails on behalf another address, logical but fuck that error message. Why is it that hard to respond with an understandable response?

Over the last week I've slowly grown to fucking hate IMAP and SMTP. You'd think after so many years we'd have come up with better servers to manage email but no we still rely on fucking decades old protocols that can't even batch requests.

To make things worse I need to attach to IMAP through node and that has been a nightmare. All the libraries suck ass and even the ones tailored towards Gmail don't work for Gmail because Google decided one day to fucking out the header at the bottom of some emails and split into mimeparts. Also why the fuck is fetching email asynchronous? There's no point at all since we requests are processed line by line in IMAP, and if the library actually supported sending asynchronous requests it wouldn't require a new object to be created for each request and allow only a single listener.

Also callbacks are antiquated for a while and it pisses me off that node hasn't updated their libraries i.e. TLS to support async/await. I've taken to "return await new Promise" where the resolve of the promise is passed as the callback, which let's me go from callback to promise to async/await. If anyone has any other ideas I'm all ears otherwise I might just rewrite their TLS library altogether...

And this is just IMAP. I wish browsers supported TLS sockets because I can already see a server struggling with several endpoints and users, it would be much easier to open a connection from the client since the relationship is essentially:

Client [N] --- [1] Server [1] --- [1] IMAP

And to make the legs of that N : N which would fix a lot of issues, I would have to open a new IMAP connection for every client, which is cool cause it could be serverless, but horrifying because that's so inefficient.

Honestly we need a new, unifying email protocol with modern paradigms...
