Hi there i’m a new here.
I’m install Cyberpanel with oneclick installer image on DigitalOcean.
My web server is working fine but mail server not working.

Jus check port is not block

nmap -p 25,465,587 myip

PORT STATE SERVICE
25/tcp open smtp
465/tcp open smtps
587/tcp open submission

and /etc/postfix# journalctl -f | grep postfix
postfix/smtp[51149]: connect to gmail-smtp-in.l.google.com[172.217.194.27]:25: Connection timed out
postfix/smtp[51149]: connect to alt1.gmail-smtp-in.l.google.com[74.125.28.26]:25: Connection timed out
postfix/smtp[51149]: connect to alt2.gmail-smtp-in.l.google.com[173.194.201.26]:25: Connection timed out
postfix/smtp[51149]: connect to alt3.gmail-smtp-in.l.google.com[209.85.200.26]:25: Connection timed out
postfix/smtp[51149]: connect to alt4.gmail-smtp-in.l.google.com[173.194.209.26]:25: Connection timed out

DigitalOcean block port 25 for new accounts. Wait for 6 months and ask support to open port 25 to send emails. Either you can configure other SMTP to your WordPress to send and receive Wp related mails using “WP Custom SMTP”
