I have a problem, I'm configuring a mail server with postfix, to handle local mail, I have a mail server, in which I going to relay all the mails that my users send, I enter to my server via telnet, and I use the command "ehlo" to know all the option he have, this option are:
PIPELINING AUTH PLAIN LOGIN to send mail through telnet from the inside of my real server I have to authenticate, authentication have to be encoded in base 64, I put my name and password encrypted, and the authentication is successful, when i send e-mails out of my domain they arrive to everyone, if i use a mail client, like thunderbird, i don't have any mistake, in my mail client i use as out going smpt my server an with the port 587 and whit any secure connexion (sasl or TLS) and all work ok. the point is that I configure my server with postfix, to use my mail server as a relay, but, every time I try to send an email he give me this error: 550 really does not allow. this means that my server don't allow any relay, but if i'm using a mail client to send mails, and i'm sending mail via telnet on my server, how is that i can not use my local server postfix for do the same. I had configure my local server with smtp_sasl....., whit smtp_tls.... and with the file of the authentication used to work with all this, and nothing work, please anybody have an advise for me, or knows another form to do this, i sink that the AUTH PLAIN LOGIN means that i don't have to encrypted my name an password with sasl o tls but how i can do that, other ask is, how can I see if my Postfix server is authenticated, or if the authentication was rejected. please i hope someone can help me with this, or show me a light.
