Got some issue with my newly setup droplet. Looks like I can’t send any email to any address. Below is one of the testing I’ve made.
This is the mail system at host vps.paskal.my.

I too was facing the email sending problem. Once, I executed the above command my all sites faced down. Both sites are down. I too tried creating several droplets just to check email sending problem and all of them didn’t work. Incoming emails comes without any problem but outgoing doesn’t delivers.
Hi @Paskal,
It seems like your port 25 is blocked. Please make sure your port is actually allowed in your firewall configuration. To do that, you can execute the following commands on your droplet :
If this doesn’t help, it might be possible DigitalOcean has closed off port 25. In that case, you’ll need to contact the support directly. You can reach them by going over to the following link
