Mike, my IP address provided by my upstream continues to get blacklisted and I don't like it however I do have one important business customer who has mail servers. On that note you hit something on the head! I had a discussion with their IT guy who told me "they must use port 25 (inbound & outbound) for their MS Exchange servers because SMTP is the only email protocol on the internet". Save me ;)
