Incompatibility with 4/6

FWIW I have the same error on *some* sites and I am not using easy-wp-smtp. I’ve seen some reports it may have something to do with using nginx, which I do, but not sure if that is the case for you.

Yes, probably. I have changed the bad line in pluggable.php where I specified literally an email ‘From’ and now everything works. For some reason . $sitename doesn’t work in 4.6 there.

Hi @evilbruce, could you please explain a bit more where exactly and to what did you change for this to work. I did find pluggable.php and I found:
// From email and name
// If we don’t have a name from the input headers
if ( !isset( $from_name ) )
$from_name = ‘WordPress’;

/* If we don’t have an email from the input headers default to wordpress@$sitename
* Some hosts will block outgoing mail from this address if it doesn’t exist but
* there’s no easy alternative. Defaulting to admin_email might appear to be another
* option but some hosts may refuse to relay mail from an unknown domain. See
* https://core.trac.www.ads-software.com/ticket/5007.
*/

if ( !isset( $from_email ) ) {
// Get the site domain and get rid of www.
$sitename = strtolower( $_SERVER[‘SERVER_NAME’] );
if ( substr( $sitename, 0, 4 ) == ‘www.’ ) {
$sitename = substr( $sitename, 4 );
}

$from_email = ‘wordpress@’ . $sitename;
}

what did you change?

I am sorry i am new to this.

thanks in advance.

Quick fix is:

comment the line $from_email = ‘wordpress@’ . $sitename;
and replace it with $from_email = ‘[email protected]’;

Hello!

I’m also having trouble with this plugin. Right now its not working and i have to use another plugin (WP Mail SMTP) because of this. K thx bai!

I have been using this plugin for many years, but the upgrade to WP 4.6 seems to have broken it. First of all, all my settings were wiped out. After re-entering everything in the settings menu, I still cannot get it to work. I keep getting the SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting message when sending a test. I have doublechecked all my settings with my e-mail host, and everything is OK. Will look into using another SMTP plugin.
