    Version: 2.1.3 Build 20101220. Just upgraded from 1.6.9 no other probl.

    It sounds as though your PHP environment is running in safe mode. In that case, the fifth parameter of mail() is disabled. Ask your host about it.

    OK, thanks. Safe mode is off but some functions are disabled: - would any of them cause problems on running EE, you think?

    You can see on the page that you linked to that the 5th parameter in mail() is disabled so yes you will run into issues with EE sending email.

    Having open basedir set to on could also cause issue in with various aspects of functionality in EE.

    Can you check our requirements page and run our Server Wizard please?

    I am going to move this thread to the EE2.x forums for you

    Hey Krake

    Dig you ever find a solution for this? I’m working with a client who is also hosted by, and I have the same issue.

    Just to clearify, I ran the server wizard and it reported no issues - all lights green there!

    Since this looks like it was something resolved with the host, I’ll let you two continue this conversation over in Community Help!

    AndrĂ©, if this looks like something that will need to involve our help, please don’t hesitate to let us know!

    Hi André,
    To be honest, I had forgotten all about this issue…

    It persists although I just updated to EE 2.2.2, so I’m afraid it’s something should deal with. As of right now it’s not a priority to my client, but if you happen to find a solution with the host, please give me a hint.

    Hi, I do hope I can solve my problem with your help.
    I just checked, my host has safe mode off and open basedir on.
    Host is One.coms

    Before install, we ran the Wizard, all seemed well.

    Yet I get the message that something is wrong, I cannot send notifications to more recepients. Mail is send, though.

    What do I do now?

    Thanks for the advise.

    Hi everybody,

    I have the same problem
    safe mode = off and open basedir = on.

    Has someone found a solution for it?

    Would be very very helpful 😊

    Ok I found the solution for everybody who has as provider.

    change the code at /system/libraries/email.php in function _send_with_mail()


    if ( ! mail($this->_recipients, $this->_subject, $this->_finalbody, $this->_header_str, "-f ".$this->clean_email($this->_headers['From'])))


    if ( ! mail($this->_recipients, $this->_subject, $this->_finalbody, $this->_header_str))

    because of: “// most documentation of sendmail using the “-f” flag lacks a space after it, however
      // we’ve encountered servers that seem to require it to be in place.”
