Hi all,
I’ve been trying to use Mailcow with docker-compose, but had issues working outside of my LAN sometimes while trial run. If my hostname is mail.example.com, sometimes I can’t connect to https://mail.example.com, but I can connect to https://192.xxx.x.xxx at the same time. (All the X’s are the rest of my local IP address). It’ll be back to normal hours later automatically, or back to normal after I restart the server(ubuntu server).
In every tutorial, people seem to be able to connect with their FAQN normally, but not me.
Any help is greatly appreciated. Thank you so much!
Ps. My server’s OS is Ubuntu 24.04. There were 10 mailboxes and sync job with current mail server for 6 mailboxes every 20min.
