(there's actual vegan sausages. Made from soya. I doubt this is one)

There used to be this local healthfood store run by a really old north indian chap who sold really really good vegan hotdogs.

Mokubai

I did not know that. They're still reasonably nice

Journeyman Geek

I have a friend who was vegitarian, and mentioned they were nice so I looked it up ;p

Mokubai

@qwertyuiop Arguably it is difficult to tell whether there is any actual animal content in most cheap hot dog sausages, or if there is then the trouble is what particular animals were involved... but still...

@JourneymanGeek My brother does not partake of the meat products also

I cannot remember for sure, but it might be the reason we tried veggie sausages

Journeyman Geek

in The Frying Pan, 1 hour ago, by Journeyman Geek

so "meat in a tube, sometimes identified" ?

@Mokubai heh, if you check what's in your food, you end up working out what's filler and what's not

Mokubai

14:16

@JourneymanGeek Never investigate the additives and filler in processed products, that way madness lies.

Journeyman Geek

@Mokubai I typically do that

Sean

Hiya, would anyone know, on an outbound mail, if SPF records usually checked at the remote mailserver first?

In fact, is outbound mail sent directly to the receiving domain's MX server, or is it sent via the sending domain's MX server first? Mail is magic and wizardry to me

allquixotic

@Sean "email"'s core protocol is really SMTP.

Simple Mail Transfer Protocol

Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (email) transmission. First defined by RFC 821 in 1982, it was last updated in 2008 with the Extended SMTP additions by RFC 5321—which is the protocol in widespread use today. SMTP by default uses TCP port 25. The protocol for mail submission is the same, but uses port 587. SMTP connections secured by SSL, known as SMTPS, default to port 465 (nonstandard, but sometimes used for legacy reasons). Although electronic mail servers and other mail transfer agents use SMTP to send and receive mail messages, user-level client...

SMTP is little more than a text-based protocol that gets piped over TCP (usually over TLS for security these days).

Mail goes from one mail server to another simply by establishing a TCP connection and sending the appropriate data. At the TCP/IP layer, it's an IP:port TCP socket established, then send data, then hang up. That's it.

Guitar Shoe Dave

smtp servers check MX records to determine which is the primary exchange for mail for delivery.

allquixotic

Everything else on top of that -- whether the receiving mail server decides to accept the inbound mail, for example -- is extra.

Guitar Shoe Dave

14:26

yup

qwertyuiop

:30676153 Are you a mail server? Yes => No
                                 No => Yes

Feck this ghetto chat mark-fuck

Journeyman Geek

lol

Mokubai

\o/

Sean

Thanks! I think I'm getting a grasp on how SMTP works.

allquixotic

But yeah, if you send email to [email protected], the SMTP server has to query DNS to determine the MX record, which basically maps a domain to an IP address.

Guitar Shoe Dave

14:27

^^

Sean

It's sent to the sender's SMTP server first, right? So if a server sends from [email protected] to [email protected], the server sends it to a.com's mailservers, which then send it on to b.com's?

allquixotic

@Sean You're assuming a particular architecture of mail server that does not necessarily have to be the case.

Guitar Shoe Dave

yea once the SMTP recieves it depending whether or not it needs to relay the message or not.. it will query DNS for MX to find the server that handles the primary exchange. Then deliver.

allquixotic

In the very absolute simplest email setup, there is NO server on the "sending" end. Nothing listening on any TCP port. Just an SMTP client.

Guitar Shoe Dave

right on

allquixotic

14:30

You can literally establish an outbound TCP socket from any arbitrary computer on the Internet, to any other arbitrary computer on the Internet, on a port that happens to be listening as an SMTP server on the receiving side (in your exmaple, b.com), and send an email.

Guitar Shoe Dave

yeah either you can client -> direct server -> delivery.. or client provider server -> relay to server -> delivery

some providers require you to use TLS /auth if you're attempting to relay mail thats not intended for the network (spam prevention)

Sean

I think I understand. Maybe I'm going a little XY on myself

Journeyman Geek

@qwertyuiop only cause spammers are dicks and ruin it for everyone

Guitar Shoe Dave

lol

allquixotic

@Sean some companies' email setups can be very complicated and involve a lot of relays and intermediary servers; then there is Exchange, and IMAP, and POP, which are more on the receiving / email storage side of things, but that's completely different and separate than SMTP.

Sean

I've got postfix set up and running, but there's no settings I can find which point it to my domain's smtp server. The IP address of the server is on the SPF record though, so there's that. When I send out an email from @thisdomain.com on the server, as far as I can see, it's sent to the destination via the domain's mailserver, without issue.

allquixotic

SMTP is the process for sending email only, and there is no necessary connection between receiving email and actually keeping them around. You could technically use SMTP as a pretty okay instantaneous communication link between two hosts if you wanted, with no storage, like HTTP.

Sean

14:38

I'm not sure if I'm missing a settings file or that is literally how smtp can work

allquixotic

@Sean Postfix IS YOUR SMTP SERVER!!!

netstat -pant | grep post -- it'll be listening on the well known SMTP ports

Sean

@allquixotic :V So I am missing something blatant.

allquixotic

> SMTP by default uses TCP port 25. The protocol for mail submission is the same, but uses port 587. SMTP connections secured by SSL, known as SMTPS, default to port 465 (nonstandard, but sometimes used for legacy reasons).

Postfix by default should be listening on at least one of those TCP ports

Journeyman Geek

@Sean flurdy.com/docs/postfix is worth a bookmark/read

Sean

You're right, postfix is listening on :25.

allquixotic

14:39

you don't "point Postfix at your domain's SMTP server"; Postfix is your SMTP server.

Guitar Shoe Dave

Sean, also.. some providers also check incoming smtp connections to verify reverse dns to ensure that the mail server has an associative PTR record.

allquixotic

The only reason you would do anything differently is if Postfix is some kind of internal server, that needs to relay messages to your "main" server.

Guitar Shoe Dave

Sean, DNS should be fine as long as the MX+A+PTR records exist.

Sean

Last month, one of the [email protected] was blocked because of excessive spam to my personal email address, the result of lack of foresight for a PHP debug script. My local mail log was spammed with rejections from inbound.mailserver.com I think this is why I'm confused

Journeyman Geek

@qwertyuiop it did.

not any more

qwertyuiop

How do you post a link without oneboxing anyway

Huh..

I got a <Image not found> box

Journeyman Geek

14:43

you add a > in front of it ;)

Sean

If postfix is the SMTP server, how come my mx-appointed mailserver is acting as the relay? Am I missing some missing config or just being really dumb

Guitar Shoe Dave

Any mail you send to a mail server that doesn't have a mailbox on the local machine would relay by design. But ideally you would want to only allow relaying to outside hosts if clients are using tls/auth.. (I dont use postfix, i still use qmail lol -- dont laugh)

I dont know postfix

conference call.

allquixotic

@Sean Because that's how you have it set up. It doesn't have to be that way, but it seems you have it configured that way.

It's a valid configuration but not necessarily required.

Sean

@allquixotic More investigation needed then I think! I can't see a setting which would do that, but I guess it has to be there.

Either way, thanks for everyone's help! I've learned more in here in 5 minutes than spending a couple of hours trying to figure it out by myself

brass may also include small proportions of a range of other elements including arsenic, phosphorus, aluminium, manganese, and silicon

DavidPostill

@Rahul2001 You can probably say the same for almost all metals. They are never 100% pure :) (unless you pay loads of money)

Examplehttp://www.hydro.com/en/Products/Casthouse-products/High-purity/ Aluminium

Purity ranges from 99.99 to 99.9999 per cent (4N to 6N)

@PichiWuana Looks like a phone plug to me. In the uk we have the RJ11 socket on the device side and a larger socket on the wall: novatech.co.uk/products/cables/networkingcables/Novatech/…

Pichi Wuana

Oh...

@Mokubai Thank you very much!!

Do you think I can change it for a Ethernet plug alone? Something simple? Or should the Internet provider come to my house?

Mokubai

@PichiWuana It depends if it is connected to your phone system...

If it's not connected to the wires in the street then you can do what you like with it

Pichi Wuana

@Mokubai You mean that if it's not connected to the wires in the street, I do can change it for an Ethernet plug?

Mokubai

@PichiWuana If it's your home wiring you can do what you like with it. At least that's how it works here... Whether the cable behind the walls is usable for ethernet is another question entirely...

Pichi Wuana

I understand
