delivering memory-to-memory to the local tcp/ip tcp port is a noticeable 
overhead, especially given that nearly all Imail servers have much idle 
MHz,a and given the SMTP is probably the most reliable, tuned modules in 
the IMail suite?

You're splitting theoretical hairs, there is no practical penalty writing 
to port 25, with a huge gain in portability and stability.

jeez, why bother trying to detect changes and test it when a new version 
comes out?  plus when it does change, you have to change your code, 
test,  install, support, etc.

exactly, so use SMTP for sending mail and forget the direct i/o to queue files.

The RFC SMTP protocol will always be more stable and therefore more 
trustable as a programming interface than a proprietary, undocumented, 
unsupported interface.
