Aweber, they have highly trusted servers and if your mailing list is treated correctly by you then the fees are really cheap!
There are quite a few services available. The least expensive and most stable way of doing this is probably setting up your own external email server for the opt-in mail. You will need a tool like Interspire on top of your host to do this. It's cheaper than the $10 CPM ($20 a day or about $140 a week) for low volume service from Aweber or Mailchimp, etc...
Most times, the first thing you want to do is to make sure your addresses are verified to minimize mail bounces (there are tools for that). The second would be the ability to pass spam filters (i.e. spamassasins). There are tools that help you determine that, but mostly, it's about the amount of html versus plain text in the email payload.
We do private mass mail and have a few clusters of mail servers of our own. PM me if you want to learn more about your mailer options.
There are many issues with your own mailing software is the chance of your ip being blacklisted and your emails will never inbox, your hosts can stop your mails being sent until you have sent them a section of your list and proved how you make them double opt in, they can also report you for spamming. You will need to set up cron jobs for the auto responder and you will need to take manual steps to rotate the ip.
As I have said before, aweber is the future. You can sit down for 3 hours and write a whole years worth of auto responder material, then just set and forget.
After all, if you don't keep in contact with your list then they will never buy and it pointless even having a list.
I used to run interspire email marketer, I then converted to aweber and never looked back. Let me know if you need more info.
