Color me impressed. The more I use Postfix, the more I’m grateful for it. I’m always finding things to solve problems I didn’t even know I had.

In the past week, I’ve been slowly migrating the sites I host to a new server, and I wanted to guarantee that no e-mail was lost during the transfer. The solution is simple with any MTA worth its salt: just instruct the old server to relay all e-mail to the new server. But doing that with a single SQL instruction is way to easy. Where are all those text files I have to change and make sure are properly parsed?
