gmail outbound connection

[randomUser]

Hi,

‌

Just got a probleme configuring mailserver, the gmail connection isn’t working properly

And just checked that my docker can ping gmail.com:25

docker exec mailserver bash -c "apt update -y;apt install nmap -y; nmap -p 25 gmail.com"

>> PORT   STATE    SERVICE
   25/tcp filtered smtp

Any clue on what it could be ?

You should try to connect to gmail’s mx servers. If connection will not work as follows, there is no other way than contact your hosting provider because you have blocked ports

$ nc gmail-smtp-in.l.google.com 25
220 mx.google.com ESMTP c16si12046339wrx.190 - gsmtp
