Unable to send mails from the website

Posted on August 31, 2020

Hi,

I am unable to send mails from the website using PHP mail function.

If I send the mail from an email to another email on my domain it works fine. However, on sending from the site, the mail is not received. On checking at mail-tester.com I noticed the errors highlighted in red https://prnt.sc/u8thpo

As an example, my domain name can be considered as domain.com

On checking hostname it shows the correct domain name and my fqdn is the same as my domain name.

Please help.

Hi there,

For anyone who comes across this in the future, using PHP mail might be quite unreliable as stated in the question.

Also keep in mind that port 25 might be closed for new accouts as described here:

Dedicated email deliverability platforms are better at handling deliverability factors like IP reputation. To send mail from DigitalOcean, we recommend using SendGrid:
