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. :(
Why is this? I know my dad has self-hosted an email server for about 15 years, and he only recently started having issues with his email going to spam. He was able to get it worked out, but he said it was annoying af, and he didn’t recommend getting into it now either. I think he had to talk to Google to get some special certificate or something.
Well, your dad seems to have answered your question already no?
Google and Microsoft are using spam as an convenient excuse to wall off their email gardens and to put insult to the injury, they are a major source of email spam these days.
