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!
To be fair, the SMTP RFC (5321) says that senders MUST retry sending upon a failure (source), but it only specifies that they SHOULD have a retry of 30 minutes, and an even weaker recommendation to continue to try for 4-5 days before giving up.
