True for many years. But ... VIA (and ARM'ish or Atom), especially with 2.5" or SSHD storage and fanless or with thermally speed-controlled fans, CAN be built to be as cool and quiet as a Wintel laptop (though generally not as quiet as a VIA or PPc laptop..) > If it is going in a server room or data centre then it > is ideal. > Noise aside, 3U and smaller rackmount case aspect ratios and weight, relative 'stiffness', or both are terribly inconvenient and too easily damaged for anything BUT rackmount or a good facsimile thereof (wall-mount 'flat', perhaps). > There are plenty of used Barracuda devices around out there but be > warning buying used means you will never be able to get any support from > Barracuda - or purchase updates.

But IMNSHO, Exim is at its best when it is first AND last in the food-chain, with no more than IPFW or PF as helpers. Load-balance or failover two - or a whole a pool of 'em - if one must - but life gets much hairier, myteries appear, machines fight or second-guess each other, get out of sync - and admin workload goes up exponentially with any Tinker to Evers to Chance chain of serial hand-offs JM2CW, Bill -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
