It really looks like a misdirected pointer or something somewhere, but I'm not familiar enough with the codebase to know where to start looking, or if in fact it is something else that is misconfigured.  Any thoughts on how to resolve this?

Dovecot doesn't identify itself anywhere really. I've no idea where your
firewall might be taking the name. The best I can guess is argv[0] given
to main(), but even that doesn't explain why it would break.
