Hello, When port 25 is not open at the ISP provider where the domain name is registered, then this could give a SMTP 250 or 220 error or -1 depending on settings in config.inc.php. via the telnet command or some testwebpage you can check if the port is open. Port 25 and 587 are closed, but port 465,993,995 are open. I've read a bunch of things here and elsewhere about adjusting the config file, like adjust the smtp server from localhost to the nameserver ns1.website.com. Adjusting the portnr from 25 to tls://465 or just 465 etcetera. None of these do help in getting the email working. Yes there is the possibility to request the provider to open port 25 or use a forwarding service like from Dynu.com. But is it not possible somehow to use these open ports to be able to get the email working? Thanks for any help.

I assume you want to run your own mail server at home or office, right? If port 25 is closed, then you can't do that as any mail server on the net will try to connect to your server on port 25, they will not try any other ports.
Yes indeed. So if they do not open 25, it will never work? If so then having the server at home has no longer any use as I need the email to work. Hopefully they will open port 25, and else I need to hire a VPS.
It won't work without port 25, there are workarounds that would require another server on the internet to receive the emails for you and then route the mails to a different port. But to be honest, then you can simply use that other server (vps) as your mail server directly
I saw Dyna.com has such service to forward the email. I had a VPS before with another project which also was used as the email server, but now I wanted it to try at home, except for email it runs Perfect. So I'll wait for an answer from the provider. Thanks very much for your reply, and have a great day!
Too bad, I'm only getting their mail server address and to use ports. Which are the same as setting your email client 993, 995, 465. So probably there is no way to set the DNS on their settings to their mail server and use local roundcube for emailing I guess. As I'm only bough an IP, I have no plesk or whatever at their site, so I can't create email addresses. They give no answer on port 25, except "that it does'nt work that way." Thanks.
