    Re: mail() putting IPv6 address into headers instead of IPv4 address, failing spam check

    No work for me.

    On /etc/hosts hostname it's correct.
    VPS IPV6 no active
    But HELO no correct.

    Apreciate help.

    1WwT04-0005R3-So ** abkrim@xxxxxxxx R=dkim_lookuphost T=dkim_remote_smtp: SMTP error from remote mail server after end of data: host []: 554 5.7.1 Mail (id-40291-00404) appears to be unsolicited - forged Helo: '' - resend with the code py2ery5u appended to subject and ask to have your email whitelisted (the code py2ery5u changes each 24 hours).
    Also on latest times, too many machiens with cpanel, on past work properly, now get this problem.

    On all systems,
    • /etc/hostname with hostname long and short hostname
    • hostname with a IP and IP with reverse PTR
    • On hosts disable IPV6 Centos 6
    • On hosts exim disbale IPV6

    Hello :)

    Please let us know your settings for the following options under "Domain and IPs" in "WHM Home » Service Configuration » Exim Configuration Manager":

    Send mail from account’s dedicated IP address
    Reference /etc/mailhelo for outgoing SMTP HELO
    Reference /etc/mailips for outgoing SMTP connections

    Thank you.
