I cannot reproduce this. /etc/mailname is debconf controlled, and the packages put whatever you answer to the debconf question in the file. The host name mentioned in the Received: Header is the primary hostname, which is - on systems with minimaldns="yes" - directly derived from hostname --fqdn. What does hostname --fqdn say on your system? On system with minimaldns="no", the primary hostname is derived at runtime by calling the uname() system function. If uname() returns a single-component name, Exim calls gethostbyname() or getipnodebyname() in an attempt to acquire q fully qualified host name. > > > exim4-config is generating a bad /etc/mailname that leads to many > > > troubles. > > > > What exactly is a bad /etc/mailname?

That is replaced by update-exim4.conf with a line which enabled /etc/email-addresses rewriting for sender addresses which are in the domain mentioned in /etc/mailname. Would be more straightforward here if we'd use a macro instead of the replacement. This is, however, documented in the update-exim4.conf man page. > > there is formal policy requiring us to change.

I begin to be convinced that we have a local configuration issue on your side here. Please give concrete examples, debugging dumps, configuration dumps etc which can be used to substantiate your claim that the exim4 packages are broken. > I think it is clear already what programs expect to find there. It becomes to be increasingly clear to me that the packages are indeed fine.
