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 ;)
