[exim] Odd hostname found in logs.

2007-10-07 21:17:30 no IP address found for host spam.complaints.(888)292-3827.alltel.senior.support.ticket#2-940727661 (during SMTP connection from [216.96.39.144] I=[<removed>]:25)

Has anyone seen entries like this before?

(I did remove my local host's IP from the line above. I'm not asking for
support, just asking if anyone else has any similar entry)
