Outgoing WordPress emails - Where are they?

smitty

I am having a hard time troubleshooting why WordPress is not able to get any outgoing email to work out of the box on Enhance. I assumed (.. i know, never assume) that by adding the Smart Host details that the servers would then allow applications like WordPress to create outgoing email successfully.

However, I also added the Email Role to the servers, and I am confused by what the documentation writes about creating a sendmail replacement that uses a hidden mailbox.

As for logging -- Can't find anything. Watching /var/log/postfix.log is just an endless loop of

Aug 01 18:11:11 en01 postfix/smtpd[55260]: lost connection after CONNECT from localhost[127.0.0.1] Aug 01 18:11:11 en01 postfix/smtpd[55260]: disconnect from localhost[127.0.0.1] commands=0/0

As of right now, I have:

A cluster with 4 servers
Smart Host settings installed globally, no overrides anywhere else
All servers have PTRs, HELO set, Hostname set
Email role fully removed from all servers except the master / control panel server
Many sites still have an Email Role assigned to the master server

When sending an email from WordPress without any SMTP settings, nothing is happening that I can see, other than WordPress declaring that the email was sent successfully.

Same result with a website that has no email role, as well.

Please help, thanks.

The default Enhance setup is a bit odd, it doesn't send as your customers domain but as the host domain. You might need to utilise a smart host or create a mailbox locally and configure Wordpress to send through that.

That’s because Enhance fully isolates websites and PHP natively - no CloudLinux or Docker involved - which is great for security and performance. But it did lead to some email complications early on. Thankfully, the smart host feature was added to address that.

Is there a tutorial available on how to implement the smarthost feature (with mailbaby for example ) on a allready active Enhance setup with 250+ domains?

Mailbaby might not send many of the phpmail emails onwards that wordpress sends, because they lack all kinds of features that Big Mail requires in order to accept them.

But just putting your mailbaby details as default in your Enhance Smart Host Settings will give you an idea if you want to try, they'll get inherited by all servers.

What we did here is disable phpmail and pre-install an SMTP plugin on the wordpresses. If phpmail starts spamming, it will get expensive quickly and your domains end up on the shitlist. Have a tutorial on how to generate an email account and put the SMTP data in the plugin. The email server sends to mailbaby after running it through rspamd. No delivery issues.

I know this doesn't answer your question but, isn't it a better option to use a SMTP setup in WordPress, where the website send emails through a proper email account instead? I just feel PHP mail is such an outdated practice and recepy for disaster in the long run.
