Thank you Gregor, I appreciate it! ??

Hi @capuderg,

I feel its best to summarize the problem again:

I can send emails just fine with WP Mail SMTP + Mailgun and every plugin that I’m using. I also get “Lost your password?” emails just fine, and that’s a WordPress functionality (I just checked it and I got the “set new password” email).

The only email that I’m not getting is when WordPress automatically updates itself to the next minor version. And–as you know–we only get those emails a few times per year, that’s why it’s harder to debug. ??

The “Administration Email Address” in Settings -> General is set to an address from my domain, [email protected]

I have yet another WordPress install where I don’t use WP Mail SMTP, and there I got the WP core update email from [email protected] – so these core update emails should come from [email protected] in the installation that’s affected.

I don’t think I have other plugins that use the WP filter auto_core_update_email. I searched my MySQL database for this string, but I couldn’t find anything. I also copied the WP plugins folder to my desktop and searched for this string (with Notepad++), but I also couldn’t find it.

I’m not exactly sure, but maybe this thread could help you guys (there are code snippets in it): https://www.ads-software.com/support/topic/invalid-address-setfrom/

Thank you!

Hi @capuderg,

Maybe I’m mistaken, but I think what you’re describing is not true, Mailgun didn’t even receive the email when WordPress Core got updated automatically.

Mailgun works fine with test emails (Check Email plugin) and with contact form emails (Formidable Pro).

I can’t set “Force from Email” to enabled because I need to have a different email address for my contact form. The address for that is [email protected].

I only use email addresses that are from my domain, I don’t use Gmail addresses etc. – so things should work.

Thank you

Hi @sanzeeb3,

Can you please give me a list of server variables to test on the server I’m on?

Accessing this script in a info.php file in the browser via https://www.example.com/info.php

<?php
echo $_SERVER[‘SERVER_NAME’];
?>

gives the correct server name:

https://www.example.com (changed to hide my identity, but it’s the correct one). Edit: Apparently this forum adds https:// to all URLs. I got the result without it.

Thanks!

Yes, that’s the plan if I can isolate it’s their plugin.

Hi @njones35,

I meant to say that CleanTalk integrates with Formidable, so it’s their code. They have a special compatibility code AFAIK.

Thank you

Hi @njones35,

Thanks for replying.

After reading your reply I have the hunch that it could be the CleanTalk plugin that’s causing this behavior. I don’t get any spam because of this plugin, but it might be bypassing the ReCAPTCHA in some cases – leading to an entry in their database that I still have to check from time to time, so it would be nice to limit that with a working ReCAPTCHA. So maybe CleanTalk’s integration with Formidable is a bit buggy.

I will do some tests and will follow up with you.

To add: I’ve got the newest version of WP Mail SMTP (2.0.0).

Today two of my WordPress installations upgraded automatically to the newest WordPress core version.

The installation where I checked “Force from Email” in WP Mail SMTP did send a success email.

The other installation where I didn’t check this setting didn’t send the success email, I got the familiar error (via WP Mail Log):
Invalid address: (setFrom) wordpress@

Is there anything I can do to help debug this?

Thanks

Hi @capuderg,

Thanks for the info. Looking forward to the new version! ??

Hi @sanzeeb3,

Thank you for forwarding the info to the development team.

Do you already have any news on this?

Thanks!

I have the same problem. I don’t use an MU website, but I also get the cURL error 28 with the Site Health Tool. Disabling and deleting the plugin removes the error.

Hi,

That means that a part of Sendgrid’s network is on the block list of Outlook/Hotmail. You might want to contact Sendgrid with the info from your dashboard.

Hi,

It seems that the fix doesn’t work anymore.

Today WordPress was automatically updated to version 5.2.5 (2 installations). But I didn’t get emails.

I get this error again (from WP Mail Log): Error: Invalid address: (setFrom) wordpress@

I’ve updated to WP Mail SMTP version 1.7.1. Did you include the fix in one of these versions? The patched version from a link from this thread did work.

Thank you.

A copy and paste answer – is that all you can do?
