Exim only uses gethostbyname for resolving email addresses if you
configure it to do so. You already remarked that it could resolve MX
records. It does all this by calling the DNS resolver functions
directly from the lookuphost router, by default.
The case you were hitting was its use of uname()/gethostbyname() in
order to find the name of the local host. This can be overridden by
setting primary_hostname in the configuration file.
