Dealing with quotas on VPS with Procmail

The new vinstall for procmail installs a procmail that honors VPS
quotas. To get the new procmail or upgrade your existing procmail,
just type 'vinstall procmail' on your VPS.

If you don't want to upgrade, the following still works:

To work around procmail not reading VPS quotas, you'll need to pass
the mail along to ~/bin/imail for final delivery (and failure if the
user is over quota). Add this as your final procmail recipe:

    ## this is in ~/usr/home/<user>/.procmailrc 
    ...
   
    ## some procmail recipes
    ...
   
    ## spam assassin stuff goes here...
    ...

    ## check quotas and deliver
    FROM=`formail -x 'From ' | awk '{print $1}'`
    EXITCODE=""
    TRAP="/bin/imail -f $FROM $LOGNAME"
    HOST

This recipe works (it causes mail to not be written to the mail spool
and bounce a 'Service unavailable' to the sender when the spool is
full, otherwise it delivers the mail). This workaround has been tested
by me but should also be tested by YOU if you plan on using it.

This differs slightly from the October 2 version but fixes a corrupt
maildrop problem (the -f option for imail writes the 'From '
correctly).
