Also, did anything change on the MTA side of things since you wrote this article? Do you recommend an expensive one like PowerMTA? Or still recommend the free MTAs?
Also, do you start sending as much mail as possible from the get-go? Or do you gradually build it up to warm the IPs up?

Obviously, much has changed since I wrote this article (and far as Canadian subscribers, much will be changing July 1st with the new consent rules) - but here's my quick reply to your questions:
Far as transactional emails, go through Amazon SES. You won't have to worry about a thing as long as you don't break their rules (and try sending high volume, unqualified marketing leads through). They will accept adult as long as it's transactional in nature (order receipts, registration confirmations, password resets, etc...) and doesn't contain obscene content. It's easy to setup to relay through and it's dirt cheap. Let them worry about delivery (they do a nice job at it).
Far as promotional emails, it is getting much harder to build stable reputation on your own IPs not recognized as owned by a major ESP. Many will deny this, but it's true if you talk to key people behind-the-scenes involved in that industry.
It will cost quite a bit more, but starting off with an already-warmed up, well-reputed shared IP pool through an ESP and then slowly shifting volume to a dedicated IP pool is the best route.
