Hi all. I've made some significant progress with Courier, however I still am running into a problem when trying to send mail to another domain. I can send mail locally perfectly fine, however I get something similar to the following in syslog: Feb 10 10:12:52 igueths courieresmtp: id=0008FB42.4028F4F4.00000A83,from=<root at lava-net.com>,addr=<alex_snow at gmx.net>: Connection closed by remote host. Feb 10 10:12:52 igueths courieresmtp: id=0008FB42.4028F4F4.00000A83,from=<root at lava-net.com>,addr=<alex_snow at gmx.net>,status: deferred Feb 10 10:12:52 igueths courierd: completed,id=0008FB42.4028F4F4.00000A83 What could I be doing wrong to have the connection be closed by my own server? Could it be a syntactical error in esmtproutes? My esmtproutes file looks like this: lava-net.com: [127.0.0.1] I also have 127.0.0.1 in smtpaccess so that relaying is allowed...I've also looked through the courier manpage, and everything seems to be set correctly from what I can tell. Any ideas as to what I could be missing/not doing correctly? Thanks!
