So, I spent the last few days researching and then finally setting up mailcow. I got my domain name, my wildcard certificate, got all the containers up, disabled ipv6 (I don’t have it set up on my home router and am too lazy to set it up tbh), created a domain and an mailbox, etc.

Well, when testing it late last night, I found that I could receive mail but was getting timeouts when sending mail. After some googling, I found out that this will happen if port 25 is not open. Using traceroute, I found that port 25 traffic is not going outside my home network. And sure enough, I found on my ISP web site that I need to have a business account to unblock port 25, which costs twice what I am paying for internet now.

So what are my options? Is there any way around this? Do I need to host this elsewhere, such as AWS? Can I use a proxy or something that can translate it to a different port for me?

Edit: Yeah, so I just set up an alias to my existing email address. It isn’t what I wanted to do, but as many have pointed out, I’m fighting a losing battle here. :(

    Pointless. Your selfhosted e-mail will just end up in spam-filters anyway.

    Sadly email federation is on its last breath and you are better off using an external service somewhere if you want your email to actually reach anyone.

    Edit: it’s not much better on VPS you can rent either.

    Edit: and in before the person that claims they have been self-hosting email for 20 years already… yes exactly! That is why yours still works.
