Hi @aleemfirnas22

If your account with DigitalOcean is new, then all SMTP actions are blocked and you need to create a ticket with Support via the control panel and ask to un-block SMTP.
This is to prevent SPAM.

    Hi,

    Thanks @hansen I created a ticket as you suggested, could enabled mail-related traffic to my account.

    This is the tutorial I followed tutorial link , worked in local machine, now again the same problem persists. After clicked on the send button in the form from (www.amfirnas.me) it’s loading some time but not recieved the email.

    Here is the php.ini settings in droplet 

    [mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = localhost
; http://php.net/smtp-port
smtp_port = 25

; For Win32 only.
; http://php.net/sendmail-from
;sendmail_from = me@example.com

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
; http://php.net/sendmail-path
sendmail_path = "/usr/bin/msmtp -C /etc/.msmtp_php --logfile /var/log/msmtp.log -a gmail -t"

    Thanks

How did it work on localhost? What tutorial did you follow?

Make sure you’re connecting with it over IPv4, not IPv6. It seems like DO is blocking IPv6 SMTP traffic.

And for what it’s worth, you can test by connecting with Gmail’s servers with the following:
$ telnet smtp.gmail.com 587

Then to test with IPv4:
$ telnet -4 smtp.gmail.com 587

If you see it trying to connect (and failing) with IPv6 with the former command, but succeeding with IPv4 in the latter command, you’ll need make your droplet use IPv4.
