All of them are logged by 'smtp'. I also run amavis+sa, i don't bounce spam,
never have accepted mail for invalid recipients (that I know of).

I'll try this out if you think it will improve things...just to give you a brief
idea, it isn't a large amount of mail getting sent to hotmail either...maybe 250
messages per day, between the hours of 9am-5pm, then about 250-500 coming back
in during those hours as well.

Thanks,
