1. Cutting down on mail. Write to the Direct Marketing Association, or visit DMAChoice.org. This will eventually remove his name from reputable mailing lists. But those he has donated to can still solicit. Next you have to write to each sender and request removal. I recommend PaperKarma to speed the job. Unfortunately organizations sell their lists, especially names of small donors. So it never really ends without constant vigilance, but you can slow it down quite a bit.
2. Phone calls are harder unless you want to screen all of his calls. If he has VOIP (Triple play type package with voice), there are a number of options that might help a little. Some phones can announce the caller, but convincing him not to answer is the problem. There are phones on the market that limit incoming calls to a restricted list...you could set it up and give as a "gift". Some have programmable buttons with pics for dialing out.
3. Does your father have a Power of Attorney? If he has done this, or is still willing, then it is much easier to take over finances when the time comes. Otherwise, you have to convince him or take away the tools for spending. There is a card, TruLink, that allows restricted spending, which can give him some limited spending ability, but blocks those not on the 'list'. Guardianship is a last resort as it is expensive, time-consuming, and public. An estate attorney can help with this.
As a Daily Money Manager(DMM), I hear about these issues all too often. Sometimes parents won't let their kids take over, but are willing to let an outside professional help if the approach is made respectfully. In cases like this, it can be an overwhelming chore for families. I don't know your location but you can find a local DMM by searching www.AADMM.com. Dementia is heartbreaking and I wish you luck and patience.
