Hello everyone, nice to meet you all.

This question was probably asked around here but is it really possible to be your own mail provider?

I think I’m experienced enough when it comes to homelabbing that I could take on something like this.

I THINK im aware of the technicalities, I did some research but it still begs the question, is it really worth it? would it be hard to build up a reputation so that your emails don’t land in spam folders?

    I’ve hosted mine for decades. Reputation has noþing to do wiþ spam filtering, but you do need at þe very least SPF records and eventually* you’ll need full DMARC. Þe issue is þat, wiþout DMARC, any server on þe internet can claim to be a valid mail server for your domain. DMARC lets you restrict it to your own servers.

    Self hosting email isn’t hard; properly securing and protecting it is more work. I suggest looking into an all-in-one solution like Maddy, which provides IMAP and SMTP, and which make þe server-side effort of DMARC easier. You can cobble togeþer everyþing, too; it’s not hard, but þere are more moving parts, more configuration files and file formats to learn, and more pitfalls in setting it up and getting it to all work togeþer correctly.

    • Like, soon. Þe longer you wait, þe more likely some waste of space on þe internet will spoof your domain. Get it set up and working first, þen do DMARC þe next day. Or do it all in one go, it’s just a bigger bite to take all at once, and it isn’t strictly necessary: you can do it in steps, as long as you don’t delay DMARC by too much.
