    Hello all,

    I have a problem with sending mail from an website.

    searched google, but cannot find a solution
    With al hosted(mail+web) on VPS there are no problems

    rDNS is set for server FQDN

    Website is hosted on VPS with the p4 version of ISPConfig
    The mail is hosted on an other server (hosting company, will move to VPS sometime)
    DNS a records pointing to this mailserver (usin ISP DNS)
    MX records pointing to this mail server

    The site is made with CIBonfire 0.7

    When sending mail with SMTP on port 587 get this errors :
    Code:
    220 mailserver.mailhoster.nl ESMTP Exim 4.84 Tue, 28 Oct 2014 23:24:50 +0100

    Unable to send email using PHP SMTP. 
    Your server might not be configured to send mail using this method.
    
    Can anyone tell me what the problem is.
    what i can do, or is it a problem with the mail server from the other ISP (they say there's nothing wrong with their server)
    used the perfect server setup debian wheezy with postfix (running almost a year without problems)

    is this something with postfix?
    there is NO email domain present in ISPConfig
