Up until recently, my site was sending emails out correctly. I've tried disabling plugins and enabling again, this did not work. I also tried the WP email smtp, this doesn't seem to be working either (I'm not entirely sure I've set it up correctly). The oddest thing is that all emails going out from the site were working up till a couple days ago. Not entirely sure what the cause of this might be.
Does anyone have any suggestions or help?
