I don’t know about a complete solution, but I’ve been able to get this one working.

Email Authentication Issue

If it becomes a large enough issue, I imagine someone will create a plugin for it. Until then, this is a work around.

Integrating something like this does not affect WordPress integration as far as I know. It’s just the email function. I imagine WordPress would have the same issue sending out emails unless you use a plugin like this there as well.
