Email into SPAM

[Mirco]

Hi I have a problem with sending email from LM5:

I use this setting:

Code:

local settings = {
    -- "from" field, only e-mail must be specified here
    from =  email,
    -- smtp username
    --user = '',
    -- smtp password
    --password = '',
    -- smtp server
    server = '192.168.206.70',
    -- smtp server port
    port = 25,
    -- enable ssl, required for gmail smtp
    --secure = 'sslv23',
  }

The email is marked SPAM and the server output is:

(I deleted the "from" and the "to" email and replaced with "***")

from=<***> to=<***>
proto=ESMTP helo=<localhost>
Nov 26 14:37:33 smtpservice1 postfix/cleanup[23052]: AAD0E255: message-id=<>
Nov 26 14:37:33 smtpservice1 opendkim[22852]: AAD0E255: can't determine
message sender; accepting


Can someone help me?

Thanks
