Milter-greylist

I am seeing this in my maillog:

Aug 19 13:30:41 lindalee milter-greylist: unknown token "<" line 245,
skipping
Aug 19 13:30:41 lindalee milter-greylist: dump error at line 245: syntax
error
Aug 19 13:30:41 lindalee milter-greylist: unknown token "@" line 245,
skipping

Is that talking about my /var/lib/milter-greylist/db/greylist.db file?

I notice that line 245 seems to have a malformed e-mail address:

66.181.65.47    <@...>   <thomas.cameron@...>
1408455770 # 2014-08-19 09:42:50

Should I do anything?
