[ale] Mail frmo dynamic host

[Christopher Fowler]

I sent an email this am and got back an error:

<A.J.Caines at halplant.com>: host mail.halplant.com[68.105.184.54] said:
554
    <66-23-224-81.clients.speedfactory.net[66.23.224.81]>: Client host
    rejected: Mail from dynamic host (in reply to RCPT TO command)

What does that mail server think I'm dynamic?  I have a static IP.  I
also have my ip in my DNS record as buford.linxdev.com.  Do I need to
tell Speedfactory to change my entry in their DNS to buford.linxdev.com?
