I am using EC2 instances to host my site.
Previously, I have used the same server for everything (apache, mysql, email etc)... is this bad practice for a small traffic site? I am not sure how resource intensive email servers are.
So, is it better to set up a separate EC2 instance to handle email? Note that there is also an incurred cost with this.
On to the good stuff: I want to be able to send emails from my web applications (using zend framework), and also manage mailing lists.
Do people use third party services for mailing lists? How hard is it to set up / how much does it cost?
I have also heard about people integrating google apps into emailing systems... what exactly does this mean?
