@alessandro-pagliari hey, who blacklisted your server? If you are using gmail as relay, final mail will be send by gmail servers. Not by your server
@rakesh-mukundan , i install postfix as relay server , i'm using SMTP.gmail.com it's work for 1 mail , After that the ip Is in blacklist, i think Is blacklisted because the ip has 25 Port open in internet . The work around for me Is install a postfix server on a machine in another network reachable and send with that.
