how do mailserver deliver emails?
Hey...
I read about telnet and e mail specifications a few minutes ago...
And now I am wondering how those email servers like web, yahoo etc send their emails to each other?...
While using the telnet console i always need to login into the smtp-server of mine account to send emails...
What I do not understand is, how do the Sending Server A send the mail to Server B...
It seems very irrealistic to me, that A sends my logindata (that i need to authenticate with A) to B to send the mail to it... so how can i simply send an email without login in on an server... OR: how do i send emails from my own Server to another one like those enumerated above? ^.-...
I did google around thwo hours now and didnt find anything except from comercials or premade software... but that does not make me understand the underlying actions going on...

yes, i did even try some of the examples...
the problem i encounter is the fact, that - while trying to do it via telnet - there everytime occurs an error concerning authentification...
how could i, for example, send an e-mail from my own server?... i dont get that...
shouldnt it be possible to just send the information (to, from, date, message) to the receiving server without beeing in need of logging in on an premade sender server, like those above...
what if i wanted to create my own one... how could i make it send a mail O?o---
