Again, yes it's a possibility but becoming less and less likely...What % of spam is currently sent from a residential connection? I've got loads of spam IPs or check any online spam DB, it's like nothing practically (1%?).
So ideal, TSI wouldn't block ANY ports but since they do block port 25, my original question remains....What is a better overall option, use TSI's SMTP servers, Google's, or any other free/simple options?--
