In particular any comments on stability and whether you are using the FreeBSD built in amd or the am-utils port. Didn't find much on archives, but the little I found was individuals having problems. A fellow ISP mentioned he tried the built in amd and had problems, but he tried on a pre 6.X environment (may have been 4.X). Our setup has a number of front end mail machines accesing nfs servers. To distribute the load we create directories like /mail-server1 /mail-server2 /mail-server3 Each of the front end machines mounts all the servers from fstab. Problem with that is that if loading from fstab if one of the nfs servers freezes the front end machines may have problems while trying to access the downed nfs server. Right now we only have a very small number of servers, but as the number of servers increase the more likely a single downed sever will affect all of the front end machines.
