Update Issue Custom Field + email handler = fail

[Align Technology]

We have workflow with post-function "Update Issue Custom Field" to set "Epic Name" to defined one on issue creation. It working well if issue is created directly in JIRA (using Create button), but do not works if issue created using email handler.

How can I fix it.

I'm curious about this scenario too, & wondered if you'd ever figured this out for yourself, or gave up, or what?
