Cannot send email from my ubuntu 18.04.1 droplet
I have the same issue as this forum list: https://www.digitalocean.com/community/questions/port-465-587-25-on-my-droplet-is-blocked-cannot-send-email-to-my-custumer-please-help-me
I cannot send email using port 587, 465, or 25 with gmail as my smtp server. I read in the forum that this block must be removed by DO admin. Please help.
