Running on a VPS, WHM/cPanel, hosted on GoDaddy (reserve comments, I had no choice, inherited it)
Outgoing emails will get hung up in the WHM Mail Queue occasionally. I can see the Tapatalk alert pop up on my phone, and go to the forum on my desktop and see the response. The e-mail will take a random amount of time to make it through. 4, 5, 8, 12, 20 minutes, no pattern. I can force the queue but I would be monitoring it all day long.
bounce handler is configured and working
This makes me wonder, is it related to my ACP email settings? For email transport method, I am just using the default method with the -f parameter box checked. Should I instead be using the SMTP method?
