master.

i have the following in master.cf

smtp inet n - n - - smtpd -o content_filter=bogofilter:

bogofilter unix - n n - - pipe
  user=filter argv=/home/filter/bf.sh ${sender} ${recipient}

bf.sh pipes the mail through bogofilter and spamassassin and then
injects it back into postfix with sendmail. SA has recently been
upgraded to 2.50, which has a bayesian scanner built-in now, so i'll
probably take bogofilter out of the pipeline in a week or two when SA
has learnt enough...for now, it's helping to train SA.

true. but that's not what i'm worried about. i'm worried about SA's
bayesian filter database exceeding mailbox_size_limit, and causing mail
to bounce.
