Help with dmesg

[Rem P Roberti]

I just finished installing clamav with clamav-milter and everything 
seems to be loading fine via rc.conf.  But I get this message at bootup 
and I have no idea what gives:

 >554 5.0.0 /etc/mail/sendmail.cf: line 48: unknown configuration line "
 >"
 >Jan  7 23:32:32 bsd sm-mta[1307]: NOQUEUE: SYSERR(root): 
/etc/mail/sendmail.cf:
 >line 48: unknown configuration line "\n"

As stated earlier clamav is loading fine, and freshclam is updating the 
database at startup.  I would appreciate some enlightenment as to the 
meaning of the dmesg.

TIA,

Rem
