Re: [IMail Forum] IP-less Virtual domains, take two

[Matt]

Sandy, Thanks for the reply.  Obviously I wouldn't be surprised to see an app use the server's default IP, but they did tell me otherwise in response to a support question.  I took that with a grain of salt, though I'm still not convinced that it isn't possible. It should be quite easy for them though to have given IMail the capability to deliver from the default host.  It just seems like an oversight in design if this turns out to not be configurable.  Heaven forbid I ever find my server's base IP blacklisted as a result of some error or one-time event, and not have the ability to change the outgoing IP for E-mail without making everything an IP'd domain. Ipswitch, as nice as their software can be at times, doesn't play nice in a mixed environment.

Without checking this directly right now, IIRC, when IMail does *not* call "BindToIP" to bind to a secondary IP for an IP-ful host--or if there is no IP assigned to a host, e.g. it is IP-less as in your case--it makes no deliberate attempt to bind to its own (so-called) primary IP, but rather just keeps "hands off" amd binds the client socket using the generic INADDR_ANY. As a result, the OS handles routing via the routing table and will send the packets out the primary IP of the interface closest to the destination; this is very typical behavior across Windows applications and certainly not confined to IMail. This info might not be up-to-date, but if it is still current, the solution is: don't expect IMail to default to an IP that is not also Windows' default IP for an interface. It just makes for unnecessary complexity, anyway. --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/download/software/freeutils/SPAMC32/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/ -- ===================================================== MailPure custom filters for Declude JunkMail Pro. http://www.mailpure.com/software/ =====================================================
