Note that, by default, the Mailman list management software doesn't
send a copy of a message to any user who is listed in the To, CC, etc
headers. If you don't receive the direct copy due to e.g. anti-spam
filters, then you won't receive a copy at all.

I recommend disabling this feature in your mailmain preferences:

	http://lists.osgeo.org/mailman/options/grass-dev/

I've asked for this "feature" to be disabled by default, but that
hasn't happened.

I suggest looking at the PROJ_INFO output, specifically the "proj"
field. It will have the value "ll" for lat/lon.
