Hi Cami I would be willing to try, though it would require some manpower and thus has to be planned in advance because more than one team is affected (we do not administer the SQL server, only Postfix and relevant processes).
The only real problem I see is - we are not really C programming specialists... understanding code is OK, but not tampering in it without being guarded through the necessary changes.... I think although this is a semi-production system, with a simple fallback scenario it should be OK to test (quickly changing back to a backup MyISAM while greylisting not working, even if that backup is 2-3 days old) What steps would be necessary? After that I could discuss team internally.

Correct. > Could there be some problem, with regards to DB or table locking and policyd accessing the tables at same time? Well, when LOCK's occur, queries from Policyd -> MySQL will (forcefully) timeout to prevent any delay. The reason we are using MyISAM instead of InnoDB is because during testing under really high loads, we found that InnoDB would not only be slower, but it would actually crash. Perhaps InnoDB needs to be re-evaluated with the latest release. Are you able to switch your Policyd database over to InnoDB? (this will require some work, including a few Policyd changes) Cami ------------------------------------------------------------------------ - Check out the new SourceForge.net Marketplace.
