OT: looking for a new hosting service with procmail/smartlist

I'm looking for a new web hosting service that has procmail available and suppports email lists via smartlist. My current service is becoming less and less reliable (over a 10% lost mail rate for mail going out from my email lists) and since they appear to be incapable of solving the problem, and since I've been a long-term subscriber to these lists, I thought I'd ask here for recommendations for a new service. The email lists are small (<150 subscribers) and the traffic is not high so a mid-range plan is plenty of capacity (200MB, 100 email addresses, 5 email lists). I've poked about in Nancy's compilation and at a couple of the on-line rating groups but a personal recommendation would help as well. Any suggestions?
