    Hi,
    I have searched everywhere and cannot find an answer to this.
    I have a dedicated server:
    WHM 10.8.0 cPanel 10.8.1-R98
    Fedora i686 - WHM X v3.1.0

    Everything seems to be working.
    except when I attempt to send an email from a perl script I get this error:

    6 to@toaddress.com R=lookuphost T=remote_smtp:
    SMTP error from remote mail server after RCPT TO::
    host toaddress.com [11.11.111.11]: 550-Verification
    failed for \n550-unrouteable
    mail domain "host.fromhost.com"\n550 Sender verify failed

    (actual emails, IPs and domain names have been changed)

    PHP scripts work fine.
    I can even login to neomail and send mail there as well.

    I am sure I have used a correct sendmail path, etc.

    Any ideas?
