Debian 10 64b (running under vmware fusion)
So running server for a while, sorting out things and now moving work stuff and start (or try to) use email sever (migration from other platform).
No Relay, No sending to external sites. Local delivery is fine.
Webmail has same issues… so its not an external authentication issue…
Any suggestions ?
Searching docs is really not revealing !!
If you don’t mind, could you share with us here how exactly you have determined that port 25 is not blocked by your VPS provider? It is blocked by default for VPSs with AWS, Linode, Digital Ocean et al.
please understand I run my own VPS, on my own physical hardware, on my own public ip ranges.
My internet provider does no blocking. On the same host in the same ip_range is another VM running surgemail which I am trying to migrate numerous domains from.
I see. Forgive my persistence about checking for port 25 block, that is the most common reason for this sort of issue nowadays and I wanted to get that out of the way. Obviously, in your particular case it does not apply, as you say.
Moving on, could you post the content of the following entries in /etc/postfix/main.cf
If you wish to ask further questions, please feel free to start another topic relevant to your question. This thread is about Postfix and your inability to send out mail. I think that particular issue is resolved.
