I think your server activity quite huge.. so your email server can't handle it..try to set run every 15 / 30 minutes... or you contact your sys-admin for another solution

I am not so certain that the email server is having trouble. I just sent an email from the server directly to my email (outside of JS) and it works fine. See attachment.

All notification emails work fine out of JS it is just the invite by email function within groups that are not. Can you test the code again and see if it works for you?

All changes that were suggested have been implemented. I am using PHP mail as the option in my server configuration.

I just got this to work. The invite email works ONLY if the 'Message' field is left blank. If anything is typed as a message in that box, JS will block the email from being sent. I just replicated this several times.

Please supply the code fix when possible.

HI Jared,

Well, this is random issue, this is the compability code with your email server and core Joomla email API code.. since we are using Joomla email API as well.

technically, why the emails got blocked, because the system send much emails in one actions cron jobs. So thats why I suggested you to decrease the emailpercron setting.. so which the email failed to sent, Jomsocial will set it blocked. we get feedback sent / not sent from Joomla email API code.

Another solution, please you also post this to Joomla forum.

thank you

Hi Dimas,

I've found that it isn't an email server/queue issue after all. Please read my last post:

is there any group / event for testing it on your site? so it won't detected as spam by your members

Here is your code -

if (!empty($values['emails'])) {

hi Jared,

I test it, here is the videos :
#1 invitation with message
screencast.com/t/uTX1kRQ5R9u0

#2 invitation with message empty
screencast.com/t/lKuYP1dQ

and the result is fine, all emails successfully to sent.

thank you
