I installed ISPmanager on a Scaleway VPS. However I don't get mail to work.
Error code in Exim log says:
****@[url removed, login to view] R=dnslookup T=remote_smtp defer (-53): retry time not reached for any host for '[url removed, login to view]'
When I search google they say port 25 could be blocked. But when I try telnet from SSH I get the following:
[root@*** ~]# telnet [url removed, login to view] 25
Connected to alt4.gmail-smtp-in.l.google.com.
Escape character is '^]'.
220 [url removed, login to view] ESMTP v11-v6si6169821pgo.643 - gsmtp
The VPS is still empty and could be erased if needed.
