Kunena 7.0.11 & Kunena 6.4.16 – Security Updates Released and K7.1 in RC1 2

The Kunena team has announce the arrival of three simultaneous security release : K6.4.16, K7.0.11 and K7.1 RC2. Just a reminder K6.4.16 receives only securities fixes untill end of 2026, so it's advised for users to upgrade to K7.0.11. K7.0.11 is the last release of the K7.0 because it's replaced by K7.1 branch with the stable release in the corner. The translations for K7.1 on crowdin.com/project/kunena-forum-7-1 needs to be checked or improved becasue it has been generated by TM (Translation Machine).

Issues sending emails from Kunena - Error 550 in mail notification was created by rudebhoy951
Hi all,

I have been trying to get to the bottom of this for some time. I can't find this issue on Kunena already so putting it out here to see if anybody has an answer for me.

On my website, moderators typically get an email when a new post goes up. Since ~ January the emails stopped sending from Kunena. It's only on Kunena. Joomla contact form sends normally. I get a mail undelivered notification email, so it is trying to send. The error message in the email is 550 Messages should have one or no To headers, not 2. (in reply to end of DATA command)

I have contacted host, they say nothing has changed and nothing from their end is causing the issue. I have tried updating Kunena, didn't fix. Updated Joomla too, no fix.

Joomla 3.9.25 and Kunena 5.2.4

Hello,

By googling i found an issue with Phpmailer : github.com/PHPMailer/PHPMailer/issues/2128 which has been fixed then, but Joomla! 3.9.x uses Phpmailer 5.2.28 it seems this fix is only in 6 and above versions

I need to look in Kunena if the mails send to moderators are set with only BBC field filled
I don't provide support by PM, because this can be useful for someone else.
