>Description:
	
Specifying an SMTP version banner containing spaces in rc.conf, like "-n foo bar"
breaks options parsing in spamd for all versions of quoting that I could think
of, i.e. "-n 'foo bar'", "-n \"foo bar\""... The bad thing is, that "-g" is added
as last command line option, thus in this case spamd will *not* do greylisting.

 >how-to-repeat:
 in /etc/rc.conf set
 
 spamd_flags="-n 'foo bar'"
 spamd_grey=YES
 
 kill spamd and (restart machine or run /etc/rc)
