I installed Mailstation and Mailstation Plus. Everything works. I receive mail I can send mail through webmail. But I want to send mail through my DS using my SMTP server.
Because "all" ISP block tcp port 25 out of their network I have to change my smtp server in Outlook everytime I get home or at another customer. The solution would be installing/configuring a smtp server which needs authentication and SSL or TLS. The port then would be 587 or 465 (legacy?).
The only forum topics I read are about relaying outgoing mail throug the ISP or Google?! I want to be autonomous so I don't relay and I want to be able to send mail with Outlook through my DS even being outside of my LAN/ISP-network.
I configured smtp in my roundcube settings. But there is still nothing listening on port 587 or 465. Can anybody help me setup my mail server? Thanks in advance.
