sure it does, but having a single point to check for valid recipients helps especially if you have a number of mailboxes/domains sitting on some different servers :) again, it may add some layer of complexity, but when it comes to managing quite a number of mailboxes it also helps; about the "single point of failure", this isn't absolutely the case; in my email I clearly wrote that; you may setup a redundant MySQL/LDAP architecture I just avoided adding details about that to keep things clear/simple since I was just trying to coarsely describe an architecture > I am not exactly sure what the mysql backend is used for to keep white/red lists, penalty box data and in general a bunch of infos using a common mysql backend allows you to have a number of ASSP boxes filtering in a "uniform" way (since all of them will have the same data); the bayesian database, on the other hand, isn't kept inside the DB, in this latter case you'll have to define a "master" ASSP on which you'll run the rebuildspamdb, and then you'll need to copy the generated files to the other ASSPs so that they'll all be in "sync;" not doing so you will face some issues, like addresses being whitelisted on one ASSP and NOT whitelisted on another one, delaying not properly working due to the fact that a given message was delayed by an ASSP and when a second one sees the *same* message, it will delay it again.. and some more; so, when using multiple ASSPs, it's better to set them up to be in-sync and using a common MySQL backend helps a lot ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Assp-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/assp-user
