Does anybody here self-host a mail-by-proxy solution? If so, I’m interested to hear about your setup, experiences and any drawbacks. I have a custom domain and a hosted email service with a very small amount of storage. I’d like to host something locally so that I can keep all my email without stressing about the space. I also want to be able to use email on my phone and computer and a web interface for tablets or while traveling. Finally, I’d like emails that I send to be stored locally so I can search it. Does anybody else already do something like this? I can forge my own path, but oftentimes, somebody else is already doing it better.
You’re asking for a lot of pain. That’s all I can say. Like SIP, SMTP is one of the most attacked services out there. It has to be public, it has to be on specific ports, and it has to be advertised that it’s available. There’s a reason why people don’t mess with it anymore.
I’d like to hide behind the service that I’m paying for without incurring extra fees for retaining it all. I can figure out the pull side by using fetchmail or something to a server that hosts dovecot, but the sending side is confusing since I’d need something that can receive my email and send it via the service. It’s only 1 email address, so I’m not looking for a mail relay, but something like a full caching mail proxy.
Just configured your mail clients pop/IMAP server as your fetchmail target and SMTP as your hosted service.
Just use Proton or a similar service. You’re getting the same thing for free or cheap.
I just found out my emails were being marked as spam just using a custom domain through icloud mail. So I don’t envy those having to run and troubleshoot their own hosted system.
Was this due to DMARC/DKIM, SPF or something else?
No clue man, sorry
I run my own email server using mailcow-dockerized. Ironically, the problem is not enough volume.
Email archiving? You can probably find self-hosted products for that. Or any service that speaks a compatible protocol with your host can fetch mail from the host and delete it on the remote side to save space.
