Postman sending out multiple mail (Until timeout!)

  • Hi, I just had a problem on a live site that sended out 2000 email (untill it hit a hard limit).

    Tested this problem on a testserver:
    – Sending confirmation woo-commerce email with default wordpress: Just one mail
    – Sending confirmation woo-commerce email with Postman SMTPJust: Unstopable flood of email. ??

    It did not matter if Postman was sending through local or remote SMTP. Now tested it again with SMTP4DEV: same problem.

    Somehow because of Postman the source keeps sending the same email over and over. (or maybe postman is sending out copies?)

    Any information on how to fix this or look into it where the problem could arise.

    Note: I found out the same error occurs when using a resend notifications from Gravity Forms

  • Same problem on my site. Did you make any progress yet?

    Did you try to send a testmail? It generates an AJAX error, but the mail is send out succesfully. I have several plugins that show similar behavior as you describe. Some kind of retry mechanism…

    I think I found the cause and a solution / workaround. Some time ago I increased the size of the log from 250 to 1.000. Today I discovered that there where almost 7.000 log lines in de posts table. I then completely turned of logging and the Ajax error did not occur anymore.

    After that, I used a Delete plugin to delete the 7.000 obsolete posts 500 at a time. That took some time. I assume the error was caused by the log delete routine that simply took too long…

    Since I don’t need logging anymore, I won’t turn it on again. My problem is solved now.

    I’m encountering a similar issue, but it’s loop-sending a “share this event” email, not a test email.

    Any luck? I’m not getting the AJAX error like @remcovanrossum was.

    Sorry – I did not solve this.
    I switched to another plugin ?? That solved it.

    But this plugin is better… so if anyone knows what to do it would be helpful.

    Shoot. Which plugin did you find that can stop it? My hosting provider keeps suspending my website over this. I need it fixed ASAP ??

    @pixelbits I determined my issue was a vulnerability in Jetpack. I’ve deactivated it, and my email issues seem to be resolved. Not sure if you’re using Jetpack, but these email outpourings seem to be a known issue…for many years, sadly.

    Sorry for my late replies @bruschr. I’m not getting replies from this thread.

    I’m using another mail log: https://nl.www.ads-software.com/plugins/wp-mail-logging/
    But No SMTP functionality…

    I was not using Jetpack. But… maybe another plugin generates the same error.
    I will check back here in a week or so ??
