I've hit this before and the reason is the little paragraph in the manpage that states, Please note that target.mail.server.example is currently the value that exim can read from reverse DNS: It first follows the host name of the target system until it finds and IP address, and then looks up the reverse DNS for that IP address to use the outcome of this query (or the IP address itself should the query fail) as index into /etc/exim4/passwd.client. Based on your logfile, I would hazard that you're trying to authenticate to smtpout.where.secureserver.net. However, this server has several IP addresses (well, I've found four so far), and when you find the rDNS for these servers, it's *these* that need to go into your passwd.client file. smtpout.where.secureserver.net -> 173.201.192.229 -> p3plsmtpa07-v01.prod.phx3.secureserver.net 173.201.193.101 -> p3plsmtpa08-v01.prod.phx3.secureserver.net 64.202.165.58 -> smtp.starfieldtech.com 64.202.165.69 -> m1plsmtpa01-v01.prod.mesa1.secureserver.net Chris -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
