Open a credit card that allows ATM withdrawals anywhere in the world with no transaction fees or clips on the exchange rate. Verify that card is working.
You should have minimum two ATM cards ready to use, issued by different banks. Your second card is kept in reserve just in case you lose your main card or it stops working.
PO Box for mail would not be the obvious choice. Think about redirecting mail to a family member, or use a paid mail forwarding service (Earth Class Mail is one).
As much as possible, reduce any reliance on physical mail. Do things online if possible. For anything that you're not planning to close before you set off traveling, add it to a simple payment schedule so that you know which days of the month or months of the year to review things.
