Email server hosting (lemmy.brennoflavio.com.br)

I'm exploring some options to see if it's viable to self host my email account. Currently I have:

A home server that I can host the entire email stack but I cannot open the SMTP port there
An AWS account where I can create a VM with SMTP ports open to the internet and reverse DNS support, also I have a domain and AWS SES configured and approved to send emails

Ideally I would want to send and receive from my home server, but that is not possible, so I'm exploring some alternatives:

For receiving emails:

Cheap VM with postfix and my home server with dovecot, essentially forwarding all emails to my home server where I want them to be. I don't know if this setup works tho.
Keep everything in a VM, with the downside that I'll need to do extra work there as it will have all my data. If possible I don't want to go that route.

For sending emails:

Sending from the same VM receiving emails, and have everything managed
Use AWS SES to send emails in my behalf

Any input or opinion is appreciated. I'm currently exploring options, I haven't made any decisions, so if you have a better alternative feel fee to share.

Thanks!

It’s harder than a beginner would expect, but also not as bad as everybody says. It’s doable and we shouldn’t discourage everybody from trying it (but don’t use it for anything important until you’re sure it works). Just make sure you set up SPF / DKIM / DMARC and rDNS properly and you’ll most likely be fine. If you’re scared or frustrated you can use a relay for send. Receiving is easy.
