I’ve contacted the host but they say that the problem doesn’t lay in the host/DNS settings.
We have installed an SMTP plugin and tried sending another announcement through Front End PM Pro but it still doesn’t send the notification emails.
We also have tested the website by filling out an contact form which is placed on the website (Contact Form 7 plugin – by Takayuki Miyoshi) and that will send out an notification email.
We also have installed an plugin that looks if the website can send emails (Check Email plugin – by Chris Taylor) and the test emails are coming in and no errors are appearing in the debug log.
So it looks like the website can send emails but there is another issue but I can’t figure out what.
Can you help me please?
