C.20 Upgrading from 1.x to 2.x

If you are upgrading from version 1.x to 2.0, you will have to do the following:

1. Edit your script file and enclose the entire code section into:

   prog envfrom
   do
     …
   done
   

   See Handlers, for more information about the prog statement.

2. If your code contained any rate statements, convert them to function calls (see rate), using the following scheme:

   Old statement: if rate key limit / expr
   New statement: if rate(key, interval("expr")) > limit
   

   For example,

      rate $f 180 / 1 hour 25 minutes
   

   should become

      rate($f, interval("1 hour 25 minutes")) > 180
   

3. Rebuild your databases using the following command:

   mailfromd --compact --all   
   

   This is necessary since the format of mailfromd databases has changed in version 2.0: the key field now includes the trailing ‘NUL’ character, which is also reflected in its length. This allows for empty (zero-length) keys. See Database Maintenance, for more information about the database compaction.
