I'm looking for someone to maintain an smtp server for my outbound autoresponder campaigns (craigslist marketing related). Either you provide the server (with multiple IPs), or I can provide a server with 100+ ips and you maintain the smtp on it. My volume of mail is 500k/month. This will require DAILY WHITELISTING work with the major ISPs to keep the IPs/SPF records clean. You *MUST* have experience with whitelisting. All outbound emails are pure autoreplies and thus 100% can spam compliant, but it's impossible to hit the inbox of major isps without daily cleaning of the IP addresses. I will pay well for this service *IF* you can do it.
