smtp authentication - chso - 12-22-2014
Hello
I have searched the interwebs for answers, but i cant find it so now i have come to see the great gods of Sentora.
Why is it that you dont have to use user or pass to send mails from a smtp i sentora?
First i tried setting it up in a mail program, imap and SMTP
First i tried setting smtp up in my mail program without password and i could send emails to every domain i have.
Then i tried to sent an email to a Gmail, then it asked me for some relay stuff and then i tried with user and pass and then i could send.
How is it that some domain can i send an email to without using user or pass on smtp?
Thanks in advance.

Sorry for my english!
EDIT: I found out that it was only internal i could use it without pass..

Well you didn't explain that well...
1. If you send email for your domain, the SMTP server will accept them ALWAYS without any authentification as it's configured ( as long the mailboxes exist). This will not require ANY RELAY permissions, as the email final destination is your own server.
2. When you send email to gmail, you will require the email to be relayed, first accepted then pooled to be sent to gmail. For email relay you will need to authentificate otherwise spamers will abuse your server.
For SMTP authentification all you have to do is setup using email login/password same as imap/POP3.
Hope it helps and explains how it works. OK?
