No. I didn't. There is only one local transport (the default). I did a postconf -n. There are no local_ or qmgr_ related settings that differ from the default. > Even then, a 1000 recipient list should be spread across two local(8) > processes, each delivering transactions of 50 recipients side by side. > I don't see that happen, so I suspect the measurement is inconclusive. Unfortunately it doesn't. :-( Cheers, --leo -- e-mail ::: Leo.Bergolth (at) wu.ac.at fax ::: +43-1-31336-906050 location ::: IT-Services | Vienna University of Economics | Austria
