I’ve been getting the same problem over and over again, I’ve reinstalled more than 10 times, I’ve moved to a different server provider, but I can’t seem to escape it.
Inititially, I’m able to send and recieve emails quite quickly and without any trouble, then after about 2 hours I cannot send nor recieve emails at all. I have no idea what is causing this to happen, but when I look in mail.log I get the same error message.
Can someone please help, I’ve been stuck on this for a week!
