Support » Fixing WordPress » Registration email issue with 2.3.1

  • After upgrading to 2.3.1, registration emails don’t arrive at many addresses. Downgrading to 2.2 allows emails to the same addresses to go through.

    I then did a fresh install of 2.3.1 (not an upgrade), and the same issue occurs. The registration emails via 2.3.1 will get through to less than 1/3 of the email addresses I try (yes, I’ve checked spam folders, and reset one address so that no spam checking occurs!). Those same addresses work fine in 2.2

    Is there a difference in the way 2.3.1 handles sending out emails that might cause this difficulty?

    (With the fresh install, there were no plugins, the default theme was used, etc.)

  • I have the same problem.
    I was also in 2.2 and email alerts worked fine. Since upgrading in 2.3.1, emails notifications don’t work anymore.

    PS : I apologize for my english :).

    After more poking around, I discovered that the registration emails that were not going through (at least the ones I could test) were failing due to a “550 Callout verification error”. I contacted tech support for my webhost (where my email is hosted) and they turned off “callout verification” (whatever that is), and that solved the problem.

    I’m still concerned that WP has changed somehow the method of sending emails, because going back and forth between a WP 2.2 and WP 2.3.1 installation reproduces the problem each time.

    Same problem occured with me after upgraded from 2.3 to 2.3.1. I checked the code of 2.3 and 2.3.1 on trac(
    There did have some differences lines in wp-mail.php, but I dont think it is the cause of problem.
    I hope somebody can go through with this problem.

    Greetings to all,

    I think I have a bit of info to help some of us.

    I actually have had the same problem since yesterday when I upgraded to wordpress 2.3.1
    I tried everything ranging from following all instructions to upgrade to reinstalling new fresh copies of 2.3.1
    It seems like an installation problem because as soon as go back to wordpress 2.3 it works fine.

    However, when I did an installation using fantastico ( I m hosted by BLUEHOST) it worked fantastically. So, I stumbled accross a magic solution but I don’t claim to fully understand why the mail function behaves differently in wordpress 2.3.1

    Try fantastico if your host enabled it. If not. . . .I have no answer. SOrry

    I have found the solution!
    Open pluggable.php under wp-includes folder. delete the following code (line228), or make a comment mark before it.
    //$phpmailer->Sender = apply_filters( 'wp_mail_from', $from_email );
    It works well with me.:-)
    Good luck to yours!

    Good job redhorsecxl !
    It works fine for me.

    I tried redhorsecxl’s suggetion but am still not having any success.

    I am having double the issues because I’m trying to get a contact page working as well!!!

    any help here would be great.



    You are great redhorsecxl! A simple comment makes everything fine.

    This solution works.

    What a great solution! Thank you so much.


    Don’t know how you figured it out but it works great, thanks! I’d love to know why this is.

    Of course, I still get an unattractively formatted “from”: Instead of a name and email address. I’ve had this problem since before any upgrades.
