I've got the bounced email feature in use on my site. I get non-stop complaints from users with @btinternet accounts. They are constantly being blocked. Looking at the log, I see many of these errors. Code: <****@btinternet.com>: host mx.bt.lon5.cpcloud.co.uk[184.108.40.206] refused to talk to me: 554 rgin02.bt.ext.cpcloud.co.uk Service not available - access denied Not sure if I can extend the timeout on my mail server or if this is just a s**t service BT are providing Anyone else get these issues?
