What are the processes I need to go through to make sure emails sent from my web server are not rejected as spam? This question is for legitimate site emails that members have requested like a daily newsletter which is generated and run in a nightly process, as well as confirmation emails.

Take a look at the service these guys offer
In most cases it ends up being better to just integrate with their API. I run a website myself and use their services and they are way better than anything i could write myself.
Even if you don't use mailchimp take a look at the contents of one of their emails and pretty much copy it - then it should go through. I think you need to collect a few details about your user such as their name etc and personalise each email.
Also, think carefully about the amount of emails you will be sending. If it's enough for your ISP to blacklist you then you may end up with no Tinterwebbage.
Hope this helps
