I've been away for the last two months and did just this.
- I had informed delivery at my home address and have had it for a few years now. It's great
- I have a mailbox at VirtualPostMail in LA
https://my.virtualpostmail.com
- I set up a temp forwarding order for the two months to send mail from the house to VPM.
I would get the usual notifications each morning about what would be coming to my home address. A day or two later, they would show up at VPM after being forwarded, and I could get it scanned, shipped, or trashed. Pretty flawless.
Is that what you are trying to achieve?
