I've installed on a brand new server, the last version of KeyHelp (20.0), on Ubuntu 18.04.
Problem is that I can't send emails. I already had contact with server provider, and is not blocked anything.
When I try to send email, it goes on Mail Queue, and gives error, for example:
I'm using CloudFlare but I've pointed all DNS records (spf, txt, dkim,...).connect to alt4.gmail-smtp-in.l.google.com[220.127.116.11]:25: Connection timed out
Do I need to unblock anything in the KeyHelp panel to send emails?
Congratulations to all team.
