Which OS are you using ?
Can you try to run a SMTP test from a simple Python script, such as:
import smtplib
s = smtplib.SMTP('mail.communi.tv', 25)
s.login('dev@communi.tv', 'ctvdev05')
s.sendmail('dev@communi.tv', ['dev@communi.tv'], "TEST")
s.close()
Do not forgot to run your test with the same user as your web server. Some Linux systems do not accept SMTP outgoing connection from the web 'user', for example…
Anyway, there's something wrong with this setup:
telnet mail.communi.tv 25
Trying 217.116.16.4...
Connected to mail.communi.tv.
Escape character is '^]'.
220 bandalatina.com ESMTP
EHLO free.fr
250-bandalatina.com
250-PIPELINING
250-8BITMIME
250 SIZE 15000000
Your email server does not report support for authentication (AUTH), whereas you are explicitly authenticating on the server (smtp_user
, smtp_password
). It should report something as:
250-AUTH PLAIN
for example.
