why do large posts fail from gmane?

I much prefer gmane over a web browser for lists and so forth, but large posts fail to this particular list. small posts work fine 100% of the time. Just thought that I'd mention it.

Maybe it's more widespread and is a google groups issue across all e- mail lists when using gmane? the folks at gmane.discuss say everything's fine with gmane. oh, gmane means <http://www.gmane.org/

, which is a very neat e-mail to nntp gateway, by the way.
