Imagine you being one of my clients. I've sent you an email and on the bottom is a footer that reads. "Sent from X10hosting." What would you think. Maybe this idea should be put to a vote.
Imagine me being one of your clients. I send you an email and receive no response, and go to another service provider. I look in my spam folder 14 days later and see your reply in the spam bin because the entire server got black-flagged because of there being no footer.
That's the counter point, and frankly x10 and the non-abusers are tired of having to get the servers unblacklisted because someone felt free hosting meant they could spam thousands of folks without a reason. If this does indeed help, it's a small price to pay.
Edit: I know this si a bit harsh the way I worded it, but that's my hard-as-concrete position on the issue. Mostly cause it's never just 1 or 2 people reporting their mail is blacklisted - it's 10-20+ who report, and probably closer to a few hundred (given the thousands of accounts x10 has) who can't be bothered to post to add their voice, or who see the issue's been reported so they don't add to it. That's a lot of people it affects every time it gets blacklisted. Anything that can be done to prevent it from getting blacklisted -should- be done, and a footer certainly helps.
Edit 2: Quick thought; isn't it yahoo or hotmail that adds a footer to all their stuff as well? Course the difference there is you tend not to use them as a commercial business email, but the same can be said for using a free hosting service to do the same. If it prevents/hinders abuse (and it certainly seems to in the case of hotmail and yahoo), then I'm all for it.
