    Hi there. Our server is currently rejecting our SharePoint outgoing emails with the following error message:

    2014-12-03 09:41:00 H=(TSSERVER) [IPADDRESS]:57319 rejected MAIL <>: Access denied - Invalid HELO name (See RFC2821

    I have added the static IP address to the following without success:

    Sender verification bypass IP addresses
    Trusted SMTP IP addresses

    I have also added helo_accept_junk_hosts = lsearch;/etc/helo_accept_junk_hosts
    where helo_accept_junk_hosts contains the IP address but I'm still unable to solve this problem. The version of Sharepoint that we are currently using does not allow me to specify a password for the SMTP account, just simply the mail server and the email address.

    Please advise

    Kind regards

    Hello :)

    You must authenticate with a valid username/password in order to send email via SMTP.

    Thank you.
