Cyberpanel+Digitalocean Can't send email (But still receive)

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

    Hi just figure out my mail is working fine cause Do block port 25.
    Open ticket to DO support they will allow smtp port.

    Thanks

    FYI. I think that DO+Cyberpanel oneclick installer have a little bug.
    After installed email not working need to remove dovecote-core(v2.3.11) and re-install again(v.2.3.7) and dovecot-mysql.
