Tonight I ran into a harsh realization that the setup I’d intended to use for mail administration, Postfix Admin, has no facilities for editing server-side filters. Therefore, I’m moving my old, highly modified vMail.Admin install over to the new server.
Tonight I got everything working and tested except for the web-based front end for Postfix’s database. That shouldn’t be too hard to get going, I just don’t feel like working on it any more tonight. After that is going I will be shutting down mail on the old box and moving it to the new one. During this time you may (read:will) experience problems having mail delivered, checking mail, the works.
Due to how email works nothing should be lost, it might just take a while to arrive. Just keep using secure.nuxx.net for pop3s / imaps or SquirrelMail and everything will work fine.
