Bug overview description.
@rebane: Tho the DMail API seems to be undocumented I guess /dmail/show.xml?id= should not return

<response>
<success type=""boolean"">false</success>
<reason>
Unexpected error (cfcf61af04fc02eeaedacf6247d0e502)
</reason>
</response>

(I did send the login and API key with the request)

What part(s) of the site page(s) are affected?
DMail, API

What is the expected behavior?
Should return dmail information.

What actual behavior is given instead?
500 error.

Time of incident. (If applicable)
N/A

Can you reproduce the bug every time?
Yes

What steps did you take to replicated this bug?
N/A

Errors or other messages returned. (If any)
500 error. Error code: cfcf61af04fc02eeaedacf6247d0e502

Bug confirmed. Assigned internal ID #620.

DMail doesn't have code set up for allowing API access and there is no templates set up.

This ended up fixed but I forgot to update the forum. Enjoy your DMail API working instead of throwing errors.
