My WordPress droplet on Ubuntu 18.04 cannot send emails via wp_mail() function.
I want my WordPress droplet to send emails via wp_mail() function, not an external SMTP plugin.
How to I fix this problem?

×Hello,
Could you please let me know if you’re receiving any error messages? Can you please post the output of this command? It will check if your Droplet is able to communicate over the ports required to send emails externally:
Question
nc -vz smtp.gmail.com 25
Some accounts have SMTP blocked default due to abuse and the output will help us to see if you’re having this issue.
Looking forward to your reply.
Thanks for confirming this.
Do you receive any error messages? How exactly you’re testing the mail functionality?
Looking forward to your reply.

No error messages.
I test the mail functionality using the following URL in WordPress Admin:
wp-admin/tools.php?page=health-check&tab=tools
It says:
“We have just sent an e-mail using wp_mail() and it seems to work. Please check your inbox and spam folder to see if you received it.”
But I never receive any emails at all.
Hello, I tried this. I am getting the following error:
“`Connection timed out
Network is unreachable
In case anyone else gets here via Google, you have to install sendmail:

apt-get install sendmail
Test it by running:
echo "email body" > mail.txt
echo "Subject: hello" | sendmail -v RECIPIENT@gmail.com < mail.txt
^change “RECIPIENT@gmail.com” to your email address for testing.
While it’s sending check the status messages. The Google server may block the email from going through because it thinks it’s spam. Going through the fun process of setting up SPF and DKIM now…
Just following up on this as I finally got it working. It was the SPF the whole time.
Instead of v=spf1 include:_spf.google.com ~all
I had to specify the originating IP address:
v=spf1 ip4:999.999.999.999 include:_spf.google.com ~all
Of course replace the “999.999.999.999” with your droplet’s IP address. I had to wait overnight for this to fully propagate but now Wordpress is successfully sending emails to Gmail without getting bounced. It’s going to the spam folder but at least I can change my password and do other administrative tasks.
