• Hello,

    This plugin has worked for years, but only recently without changing the site at all started to give me this error.

    Invalid “To” e-mail address “<>”

    I have made sure to put a “To” e-mail address in the settings but when I check the logs the “To” field looks like

    To: <>, [email protected]

    with [email protected] being an example of the e-mail I put in. I am the administrator and I have not received any e-mails either.

  • Can you output your diagnostics here (obfuscating any personal information as required)

    Ok, where is the diagnostics found for the plugins?

    Click on Post SMTP in the left hand side bar.

    That will bring up the main Post SMTP Setup page.

    In the 3rd column, Troubleshooting, click the 2nd option down, “Diagnostic Test”

    Copy the information in the panel and paste here.
    (If you are worried about having your domain on show, first paste in a Notepad type app and search and replace your domain and replace with something like yourdomain.tld)

    It doesn’t contain any passwords, or other personal identifiable information.

    First off, you appear to have WP Mail SMTP and Post SMTP installed at the same time.
    I’d remove WP Mail SMTP first, and I’d also switch off the Set Email Sender plugin until you’ve sorted this out.

    You also seem to have a phpmailer_init Action(s)cn_wpplug_setemailsender, email_configuration_mail_bank which I’m not sure where that’s coming from. That suggests it’s playing with the mail settings in some way.
    Hopefully disabling both of the above plugins might move that away.

    You’re also running a very old version of PHP (5.4). Any chance of upgrading to a 7.x version (7.1, 7.2 work for me, I’ve had minor issues with 7.3).

    Also, if this is a production site that is live and viewable to the world, I’d remove the “Better Search Replace” plug-in. That plug-in shouldn’t be left on a WordPress install once you’ve done all your searching and replacing. There aren’t known ‘hacks’ but it has the potential to be ‘abused’.

    Let me know when you’ve disabled those two plugins and see what happens when you try to send a test email. (On the same screen as the Diagnostic link).

    Regards

    Chris

    Ended up figuring it out. Those plugins were not the issue, but something that changed for some reason elsewhere in the site. I appreciate your time and help today.

    Not a problem. (Forgot to mention you were using Post SMTP version 1.7.7 which is some way behind the latest version of 2.0.2 )
