Have you thought of migrating off of sendmail? Qmail + VPopmail would be a greta solution. Not only do you get rid of the hasle, and security risks of having so many system accounts, but you get speed an reliability thrown in. www.inter7.com/vpopmail/ As far as scalability... the main maintainer has developed systems with over 50K users per domain, and i have setup the system on isp's with over 2K virtual domains at about 50 accounts per domain. Take a look at it. Michael Barnett writes: > > Everyone, > > We are redesigning our email scheme, and I am looking for an alternative > to pushing passwords around on dozens of machines.
