Hi Frans,
thanks for testing.

Good.
The original bug surfaced in joeyh's regression testing installations
and could be reproduced in a normal system.

That sounds like a DNS issue. Exim tries to resolve its own hostname,
and if that cannot be done, it waits for a DNS timeout. Usual remedy
is making sure that the local hostname (hostname _and_ FQDN) is
resolvable via /etc/hosts, since for a new install the hostname is
unlikely to be available via DNS. See the second FAQ question in
README.Debian

That's a new one. Can you try setting EX4DEBUG to a non-empty value
and see where the delay is happening?
