I've got a small side project that I'm getting started, and I'm using Amazon SES for it at the moment but I need to look into options because SES can't do everything that I'm trying to do. I send emails such as password resets, user opt-ins (new content on the site that they're interested in), and private messages between users. I also receive email directly into the site, mostly so sending private messages to users via email allows them to reply to the mail from their email client. At the moment I don't really send newsletters or any kind of marketing email, only emails that are "part of" the app. The thing that doesn't work for me with SES is the ability to have email aliases for things like support@myhost.com and have it forward to my personal email address. It doesn't matter if you've verified your personal address with Amazon, they won't send emails from unverified senders so Postfix aliases won't work. I'm not really sure what's a good way to handle this yet.. I don't want to subscribe to something like Sendgrid for this one use case, it's way too expensive for me when I'm just trying to get this thing started. Does anyone have any suggestion on a decent place to host my MX that won't cost a fortune so I can do email aliases like this?
