Maybe once a month, I’ve never actually witnessed it, I just sometimes find traces of what looks like a feathery murder scene. And she sometimes brings me a (dead) bat…

My weekend mornings are doing it for me this summer. I just sit in the garden watching the birds, and my cat running after them, while I drink coffee for at least an hour.

Although I agree that if it’s a small business, it’s better to outsource it to an established business but if you’re serious about doing it yourself, check out OpenDesk/OpenCode. Also, why use your own hardware? A VPS is much more reliable.

Basically every serious mailserver package has imapsync included. I don’t know what kind of hardware you’re running and what you expect from the server doing the copying but running webmail, search indexes, antivirus, etc will cost you ram.
