"Bad Host Name" Error Message

[Gerard Seibert]

I continually receive an error message about a bad host name. This is the 
error message:

Starting cron
Local package initialization: printerDec 7 21:20:44 BeerStud at rcn lpd[438]: 
Get_local_host: hostname 'BeerStud at rcn.com' bad
2004-12-07-21:20:44.236 Get_local_host: hostname 'BeerStud at rcn.com' bad

This is the contents of my 'rc.conf' file:

blanktime="3600"
Hostname=BeerStud at rcn.com
ifconfig_rl0="DHCP"
linux_enable="YES"
nfs_client_enable="YES"
saver="logo"
sendmail_enable="NONE"
usbd_enable="YES"
lprng_enable="YES"
clear_tmp_enable="YES"
ntpd_enable="YES"
ntpdate_flags=" -b 0.pool.ntp.org"
inetd_enable="NO"

I have tried different combinations of 'host names', but without success. 
My ISP is "rcn.com."

Thanks in advance for any assistance possible.
