postfix can not start

[Daniel J. Luke]

You upgrade mysql and it removed a library that postfix depended on. (/ 
opt/local/lib/mysql5/mysql/libmysqlclient.16.dylib).

When you removed and re-installed postfix, it found the newer mysql  
library and worked again.

One way of dealing with this sort of thing would be to have a staging  
server where you can test upgrades before you push them to your  
production machine (or if you have a cluster, you might be able to  
remove one machine from the cluster, test the upgrade on it, and move  
it back into the cluster once you are confident that the upgrade  
worked).
