Dear Mark,
I have yesterday late evening migrated server to Siteground
In Easydiscuss emails sent through cron
> Automatically Spam is been added in subject line
> Email not going to all recipients, only to select recipients
When checked with Siteground as per them -
"The thing that is adding SPAM in front of your emails is not coming from our server. I've checked all of the anti-spam protections that we run and neither of them is enabled also neither of them is editing the object of the emails.
I presume that this is coming from plugin that you are using or from the plugin that is sending the emails.
I'd recommend you to check with the developers of the plugin as they should have better understanding of it and easily remove the issue causing that to you.
Can you help in it - what to do
