But this doesn't treat the problem of having the same settings for general outbound mail and mail for smarthosted domains (I'm not using the term "gatewayed" anymore, given the static mailroutes you're limited to with HOSTS). The idea of the global "down domain" cache was quite cool, but I believe it needs to be paired with a fully compartmentalized virtual server architecture to be really tantalizing. Even if it were able to be applied to only specific domains, the seeming advantage of FDS -- creating a longer queue lifetime that lowers the priority of messages after encountering transient errors -- comes at the expense of lengthening the retry interval, which, IMO, is the opposite of what you want to happen when smarthosting a customer domain. I often set retry intervals of 15 minutes, 5 if supported by the MTA, for dedicated secondaries. Having to delay retries is not the way to increase sensitivity to downtime _as well as_ uptime. FDS may useful if synched to the regular retry interval; setting FDS longer is just counterproductive. --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.imprimia.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange or IMail mailboxes into IMail Aliases! http://www.imprimia.com/products/software/freeutils/exchange2aliases/download/release/ http://www.imprimia.com/products/software/freeutils/ldap2aliases/download/release/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
