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. :(
They don’t bounce when the spam filter catches them. I have seen many people claiming they have no issues sending emails just for all their emails directly go to the spam-folder in my gmail account (that I reluctantly have). Maybe ask the people you are sending the emails to? Just because you don’t immediately notice the problem doesn’t mean it isn’t there.
