When you submit a message, the form appears to send the email, giving the “Your message was sent successfully” response.
However, the contact form message email is never delivered.
In a recent test, I finally received the auto response email some 15 minutes later (mail 2), but it also sent me two identical emails. The contact form message email never arrived.

I do not know what the problem is. I looked at the settings and it is just a basic set-up…
Any ideas?

Thanks!

So my server says they block php mailer and unauthenticated SMTP emails.
Fine. I installed WP Mail SMTP, filled in the settings, and now the contact form has an error message.

I did the test email through WP Mail SMTP, and it gives an error. It doesn’t seem to authenticate…?

Here is the full error, with my actual emails, domain name and passwords changed for my privacy:

The result was:
bool(false)

Okay, I deactivated WP Mail SMTP which would not authenticate my email login even though it was the correct info. I installed and set-up Postman SMTP with the same settings. However, it has instructions to set up a Google Client ID and Client Secret so as to make gmail allow wordpress to send/receive mail, aka it is more secure, which makes gmail not block emails coming from contact forms.

So Contact Form 7 is okay, just will not work on its own with many servers or gmail. Just an FYI for anyone with a similar problem.

It took me all afternoon to figure this crap out…UGH.

@eyeheartdesign are you saying your issue was resolved by installing Postman and configuring the Gmail API?

WP Mail SMTP which would not authenticate my email login even though it was the correct info.

Sounds like the info was actually not correct.

So Contact Form 7 is okay, just will not work on its own with many servers or gmail.

Well… that’s semi true. Contact Form 7 only generates mail. It is not responsible for delivering mail. Many WordPress hosts do not support the SMTP settings that WordPress ships with. That’s why we have SMTP plugins.

Postman has a Connectivity Test, Email Log, Configuration Wizard and many other tools to assist you in getting your WordPress email to send reliably.

Glad you got it sorted out.

Hi,
It seems that the problem was on the side of my web provider (one.com) who deleted my contact adress and aliases.
I had some problem to re-create it because there was a technical problem on their servers yesterday, but from yesterday evening and this morning everything is OK.
Sorry for the inconvenience, everything ok with this excellent CF7 ??
Olivier.

No, my smtp port number, password, etc, were entered correctly, but WP Mail SMTP was not able to deliver the mail because it does not have the needed feature of authenticating with the client ID and client secret.

IMO, Contact Form 7 should mention the possible necessity of an SMTP plugin in an upfront manner in its help section and general description, so that people can quickly move to this possible solution instead of being given the impression something is broken.
