I use Paymybills.com, which was recently bought by Paytrust.com.

I was an early adopter (sometime in 2000) and LOVE it. I highly recommend the service.

They've consistently gone above and beyond to help me when I've needed help and take care of things for me.

I was going to switch to Bank of America's bill pay service because it's free, but I tried it for a few months and switched back - features/functionality were not as good and I didn't feel like they were very helpful.
