Thanks for your reply, Sendmail stay here. I can't go with you in this situation. The administrators view: this is big performance loss in some situation(maybe rare), and can occurs duplicate mail delivery (i tested, for a day and overhead above 150% here). I can't see clearly why good this, but i accept this is good. Just not for me and not for now. If you have a written documentation about queue mechanism please give me a reference.
