[exim] Router name lenth bug?

Hi

I have two routers:

attachments:
driver = accept
transport = attachments
...

attachments_filter:
driver = accept
transport = attachments_filter
...

And two matching transports:

attachments:
driver = appendfile
...

attachments_filtered:
driver = appendfile
...

As you see, there was a typo between the transport option of the router and
the actual transport name.

However, exim didn't detect an error when loading, even worse, IT USED THE
WRONG TRANSPORT silently...


Is this a bug?
Or is there a maximum length for router/transport names?
If so, why is there no warning about two equally named transports?
