PowerMTA / OEMpro expert needed to tweak existing setup

=> Summary We have powerMTA and oempro installed on our server. We are having a few small issues due to configuration setup. It was only recently setup and configured but we believe it was not configured correctly, and they freelancer who set it up is not responding to our requests to fix it. => Details Issue 1. OEM pro has been setup use SMTP delivery for powerMTA instead of the proper PowerMTA delivery option - we want this configured correctly. Initially the freelancer who set it up said we had to do it this way due to the rotating IP addresses but we have since discovered from OEMpro techs that it will indeed work correctly using the PowerMTA delivery method as long as it configured correctly. Issue 2. We are also getting a lot of failed mail errors to email addresses that should work. The issue is internittent - One time it doesn't work another time it does work to the same email addresses. We need this fixed. => How to place you bid Respond with the words "email marketing" at the very beginning of your bid to show you have read all the instructions - Failure to do so will mean your bid is automatically deleted. => What we're looking for I'm looking for someone who we can work with on an ongoing basis - if you are so busy that you don't have to time to follow up on support and request then don't bid. Only serious professionals who are able to follow up are invited to bid.
