Hi! In order to send mail from php applications like Wordpress you need to set up an MTA on your droplet like postfix or sendmail. You can do this with:

apt-get install postfix

Once an MTA is installed php’s mail() function can use it to send your outgoing messages.

Thanks for your prompt reply.

I forgot to mention I have already done

sudo apt-get install sendmail

Should I try postfix instead? Will it conflict with sendmail by doing so? If yes, do I have to remove “sendmail” somehow?

Thanks

I have to apologize, my bad. Since “sendmail” is installed, I do receive emails but they just ending up in spam/junk. Will do the proper adjustments.

Thanks for your help

Best

Just in case you are still trying to resolve this issue, I suggest that you add the IP of your droplet to the SPF record of you mail server’s domain in DNS.
