Just as a side note, I setup my home server with dovecot, postfix, mysql and I ended up removing mysql because it was a memory pig for a not-very big install. In your case, if you're running on an ARMv7 dual CPU box, it also isn't too big so I'd prboably not bother. sqlite or even flat files should be more than performant enough for your needs. John
