I currently have mail for ch...@isbd.co.uk and c...@isbd.net forwarded by my hosting service to a Postfix server on my desktop machine (which is zbmc.eu). The Postfix configuration is fairly simple, just accepts mail for the zbmc.eu domain and sends mail via my hosting service's smarthost.
I want to create a similar Postfix server installation on a VPS I already run so that if my home desktop machine has a long down time for any reason I can forward my mail from my hosting provider to the VPS instead. This is a simple reconfiguration on my hosting provider. The VPS has postfix version 3.3, my desktop has version 3.5.6, am I likely to encounter any problems with a similar main.cf on the older version? I realise I have to change the myorigin, mydestination and myhostname but I'm hoping that's basically all. -- Chris Green
