Unknown option: a when restarting spamd

[Geoff Soper]

I've recently moved from calling spamassasin to using spamc/spamd. Today 
I had a "/etc/rc.d/init.d/spamd restart" fail with the message "Unknown 
option: a". Googling this led me to the /etc/sysconfig/spamassassin and 
/etc/rc.d/init.d/spamd files, both of which specified the "a" option 
(the former file overriding the latter file).

What would the "a" option be and why did the two files specify it when 
spamd doesn't accept it?

Thanks,
Geoff
