HiCallMeJean

It’s not the client Mike. Screenshots are from icloud and gmail.
The SMTP relay causes the issue.

Fix it.

I’ve activated a plugin for SMTP.

WP Mail

Now it’s not possible to see the BCC option.
Guess the standard SMTP relay of the QNAP NAS is the issue.
The remedy is to install / activate a SMTP plugin from WordPress.

Thanks.

Extra information, i’ve compared the version of pluggable.php from the latest version.

pluggable.php

Both versions are the same. Just to be sure i’ve replaced it and did another test. Still i can see the BCC option.

So i’m out of options now. Hope you can find anything or have another idea.
Hope to hear from you.

I think i found the conf that is causing this issue. It’s in the wp_mail function.

Because this is running on a QNAP NAS with a WordPress Installation on it think this can be not standard. I can send you my Pluggable.php version if you want?

Double checked my settings. I thought i found something.

So i deactivated the plugin and activated it again. This seems ok now.
So i ran another test. But if i send another e-mail i can still see the BCC field.
Now i also sent a test to my Gmail client.

I’m still checking if i can bypass the SMTP option.

Just send an e-mail to a few users. I selected them with.

Screenshot select

I let one of the users send me a screenshot of the BCC, field.
Here are all the users i selected in.

Can this be because i’m running WP on a QNAP NAS?
I think for the SMTP there is a global SMTP relay…
Can this be the cause? Of can it be bypassed?

Sorry for the late reaction. But i’ve tested this on an iPhone and webmail of iCloud.
I can test it again right now.

Well that is the thing, i just tested it. I use the feature in a post to send this post to all users. (Notify Users About this Post)

I created a (test) subscriber and if i log in i see all the headers, including the BCC.

WordPress version: 3.8.1.
Email Users: 4.6.7.

I never noticed this is the previous version. Can this be a bug in the 4.6.7. version?
