Hello everyone! I’ve made my own chatmail relay. It’s working and I can send messages between users on my server. But when I try to text to users of different relays I can see only endless message ‘establishing connection, please wait…’ I’ve checked all the DNS records, and script cmdeploy dns says that everything is ok. All test passes except 6 skipped ones. I’ve read the previous topics about similar cases, but can’t find a solution. What shall I check else to make it work?
Log into the server and check postqueue -p. It lists outgoing messages that are queued up with the reason. If the reason is connection timeout or similar connection failure, it is likely that your provider blocks outgoing connections on port 25 or you have firewall configured.
Thank you a lot! I’ve done as you have said and learned that my provider really block 25 port. I wrote to them, they confirmed it and asked for explanations why I need this port. It is awful, so I decided to migrate to other provider
It is actually quite common, so maybe try to just say “i want to setup an email server” and see if they are fine with it.
