> What is Imgate? Sorry, I am not familiar with that. IMGate is Postfix, the Unix-based MTA. Len has put together a cookbook for people running PostFix inbound MXs/outbound gateways in front of IMail, hence IM + gate.
It's absolutely true that MXs should be able to reject unknown recipients at local domains during the initial SMTP envelope. One option is a script that manually synchronizes a user list on the mailbox server with an alias list on the MX; this is the method used by IMGate users and those fronting Exchange with IMail using the script in my sig. Another is real-time synchronization using a low-overhead directory protocol like LDAP; we prefer this option. A third option is automatic LDAP "pull" synchronization with a local cache for detached use. And, yes, a fourth option is manually maintaining the alias database whenever you make adds/changes/deletes to the user database; distasteful though this may seem, if the userbase is small enough to keep the hours manageable, this is far better than letting everything through. A gateway product that's not even vaguely _aware_ of the idea of unknown recipients, no matter how you were willing to enter them in, is a poorly designed product. --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.mailmage.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange Addresses into IMail Aliases! http://www.mailmage.com/products/software/freeutils/exchange2aliases/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/
