I guess I've never considered non-interactive use of send-email. But the ask() in validate_address does have default q[uit], which I suppose gets used if stdin is /dev/null? I did do an experiment adding a bunch of the random odd patterns found in kernel commit messages to see how send-email reacted before/after this, and the only things that got filtered away (i.e., no longer prompted about) were things where the user probably couldn't easily fix it anyway. In the cases where there was a "Cc: stable" that might be fixed to the proper stable@xxxxxxxxxxxxxxx, the logic in extract_valid_address simply saw that as a local address, so we didn't use to be prompted, but simply sent to stable@localhost. Now we simply don't pass that through. So, for non-interactive use, I guess the effect of this patch is to allow more cases to complete succesfully, since we filter away (some) cases where extract_valid_address would cause us to prompt (and thus quit). So, it seems you're ok with this tightening, but some comment on the non-interactive use case should be made in the commit log? Or am I misunderstanding? Thanks, Rasmus
