Hector, the submission port is not related to Git, but to SMTP for sending emails (authenticated, secure transport layer, etc).

Git actually uses either http(s) or SSH (22). Maybe you just hit a problem on the Git server.

Hi All

Why the port 587 is closed.

If you try to fetch with git the server timeout not response

I ran
nmap -sT -O git.koha-community.org

Nmap scan report for git.koha-community.org (174.143.233.17)
Host is up (0.090s latency).
rDNS record for 174.143.233.17: 174-143-233-17.static.cloud-ips.com
