My DSL provider in Arizona is Qwest. The basic service is $26 and for

another $5 they will toss you a fixed IP address. As pointed out earlier

you must have fixed IP address for all practical purposes. You may

however set

MTA even with dynamic IP but the chances are that most other MTA will

bounce your mail. However some will not. Even with dynamic IP, I was

able to send emails to my friends working for Apple. Apparently, Apple

is not very afraid of the spam or they have crystal ball to see which

dynamic IP addresses are legit.

The Qwest internet speed in Arizona vary from 1.5-7 Mps pending how far

is one's house is from their switch.

I know that those speeds look funny to people from Europe and Japan but

ISP providers in U. S. are monopolies thanks to the president Bush. A

decent speed of 10-100Mps on T1 will cost you about $1400 a month.
Qwest's modem blocks by default www hosting, MTA, and most other

services. However it is trivial to log into the modem and unblock the

ports. Qwest actually actively encourage customers to have fixed IP

addresses for purpose of online gaming and conference hosting.
I did run my own MTA with the proper domain name that can be purchased

for about $10 a year. I had no problems receiving incoming mail and

mixed success with sending mail. I did that because I wanted to learn a

few things.

My real MTA is at the University I work for and I fetch my mail via IMAP

server to my local mail client as probably most people do.
I would suggest that before you make definitive decision to run your own

MTA you try to do dynamic mail hosting. I used free DynDNS services

provided by DynDNS.com. The way that it works is that they run a honest

MTA which does virtual hosting for many servers which do have only

dynamic IP address.

This is usually extra service you get from them as their main thing is

virtual web hosting. Basic web and mail

virtual hosting is free but their real objective is to get you sign for

their paid services.
Their MTA is completely legit and on the white list so your outgoing

mail will never bounce. The big draw back in my eyes is that you must

run something like opendd which is DynDNS client in order to update

their server about your current IP address.
The positive thing is that they will run spamassassin and clamav for you.
