I'm trying to send an email establishing a telnet connection with the smtp server. I succeed to establish the connection with the port 587, the authentication works, I enter the mail from: <>
, the rcpt to:<>
and it works.
Finally, when I type the data, enter the dot and type enter, I receive a message saying :
550 5.5.0 Service refuse. Service refused, please try later. LPN105_510
I'm trying to understand why it doesn't accept to send my email. I tried by establishing a TLS connection, it didn't work. I'm thinking it might be because of the "domain" I'm giving after the ehlo
(localhost), but I have read that it was not important. If it was because of my IP address, I would not be allowed to get so far (connection + authentication). My ATM would do exactly the same operation, right ?
I really don't see what it can be. Here is the connection sequence :
Connected to smtp.laposte.net.
