[exim] logs

I am getting this in my log files a lot and am wondering why?


no IP address found for host phpbbspprt840.gmail.com (during SMTP connection from unlocktheinbox.com (mail.unlocktheinbox.com) [168.144.32.45])

no IP address found for host phpbbspprt840.gmail.com (during SMTP
connection from mout.gmx.net [74.208.4.200])

no IP address found for host phpbbspprt840.gmail.com (during SMTP connection from strong-eds-02.klga1.s.vonagenetworks.net [216.115.18.24])

If you notice every time an email comes in from wherever it always has phpbbspprt840.gmail.com attached to it.

The normal email does come in and the headers from the mail does not show this, only the logs.

Can someone help me figure this out please.

Thanks
