Hi everyone, I've just moved to a new server with what should be an identical Postfix configuration. The main.cf and master.cf files for each appear to be as similar as they can get for two different systems. The problem I've found since starting up the new server is that all mail to @mac.com addresses is sitting in the queue with the following error: -Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient------- E7EE01AA127 5562 Wed Sep 3 10:14:39 [EMAIL PROTECTED] (host smtp-mx1.mac.com[17.148.20.64] refused to talk to me: 452 try later) [EMAIL PROTECTED] [EMAIL PROTECTED]
[EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] I've done a few Google searches on this and most suggest that this error is caused by the recipient server actively blocking the sender, but I don't see why this would have been done in my case. Incidentally, I run a Mac user group and its discussion list on this server, so as you can imagine it's causing a few problems :-P Many thanks in advance, Rodti
