Make the backslash character special when logging the sender in
Postfix reject messages? Bleh.
I would prefer consistency, i.e. always log a sender or recipient
address in proper externalized form.
from=<"x@y.z> from=<a@b.c> to=<\\x@y.z"@example.com
There is a library function tok822_externalize() for doing the above
conversion. There are not that many places where =<%s> is called
with an address, so this is just some work. This avoids the need
to propagate both address versions through all of Postfix.
