I'd have to chime in and say I'm already paying almost $100 for my aDSL connection for my home. I'm paying for a static IP allocation which has been SWIP'd with ARIN and have forward and reverse DNS pointing to my domain. However I deal with on a regular basis ISPs which will reject the mail from my servers as saying they're dynamic dial-up IP space. Not that any one of them ever respond to inquires to try and get removed (RoadRunner being the most recent) from the list; nor the fact that not one piece of spam has been sent through my servers given that they are SMTP AUTH only, have extensive anti-virus scanning (which doesn't send out emails to anyone but postmaster), and spam tagging. I can understand the ISPs that don't allow hosting of servers on the DSL line and/or blocking SMTP outbound traffic; however if a customer is paying for static IP space and the ability to host servers on the DSL line then it's not dynamic. I'm not gonna pay another $50/month to have my mail server at some colo just so my mail can be delievered because some ISP doesn't want to accept the mail. I've even recently published the SPF details in my zones so any SMTP+SPF compliant machine can even verify that the message is coming from an authorized machine. Unfortunately not enough domains are doing the same. Regards, Jeremy On Sat, Mar 13, 2004 at 11:45:44AM -0800, Michel Py wrote:

<me puts the devil's advocate suit on> $50 is a lot of money; I currently send email from my aDSL address because a) my ISP's smarthost sucks b) historically their SMTP hosts have been blacklisted more than mine c) even if they did not suck (which has improved a lot recently, actually) they still won't accept large attachments or mailing-list traffic. I pay $36/mo for my aDSL. $50 _more_ sounds a lot. </me puts the devil's advocate suit on>
Besides, although this list is definitely the right place to find people that would operate a personal SMTP relay in a colo just by the virtue that it's the geeky thing to do, what does it change in the big scheme of things? All these small business customers (20 persons) that I have that use a sub-$100 "business" DSL and M$ Small Business Server + Exchange are not going to go for it, because the cost then will suddenly become $50 plus the 1U server plus my time plus maintaining it.
