I do not believe so. Lots of people drive when they are tired (tiredness
covers a range of different degrees of tiredness) and having a few
alcoholic drinks with a meal is often an easy way to relax. The problem
of driving on the 'wrong' side of the road is caused by having two
different system in Europe. For me, the 'right' side is the 'right' side
to drive on.
Sweden changed successfully now old lagging behind Britain needs to do
the same. The Brits have changed to Centigrade and measurements are now
in Napoleon's favourite format (i.e. metric). Motorways - right from the
beginning - have been built to be bi-directional (i.e. suitable for
driving on the right).

It is part of a taylor-made configuration.

I am quoting from my acl_smtp_rcpt.

I have two active sections in ACL. The first is acl_smtp_rcpt and the
second is acl_smtp_data.
deny message = [C05] Your mailserver is misconfigured. Invalid
Host Reverse Lookup. MsgX
!condition = ${if match{$sender_helo_name}{xxxxxx}}
!verify = reverse_host_lookup
comes before
deny message = [C06.5] Msg6 Msg2
hosts = ^.*[.-_]adsl[.-_].*
Jim Cheetham suggested omitting ^.* but I have reservations about
abandoning the .* because I am unsure whether Exim will do a partial
match without .*

Our Exim is purely for sending mail directly to mail servers (and
directly to a few email programs that receive SMTP mail) and receiving
mail from normal mail servers. At the moment no
broadband/dialup/WiFi/traveling users attach to Exim.
Our Exim listens on these ports:
daemon_smtp_ports = 25 : 465 : 587
tls_on_connect_ports = 465

'XXXXXX' is the best way to allow an email programme to emulate remote
mail servers for testing purposes.
