We have a facility for doing somthing like this in order to support
long-form names, such as queens.cam.ac.uk instead of the traditional but
excessively abbreviated quns.cam.ac.uk. We use a redirect router to
implement it, as follows below.
Note that we do not rewrite the message header. This is because the person
who used the "wrong" address is the sender, but rewriting the address does
not inform them that they did so, and it hides the fact from the
recipient. This is explained at greater length at
http://www.cus.cam.ac.uk/~fanf2/hermes/doc/misc/longform.txt
# The longshort table contains entries like
# queens.cam.ac.uk: quns.cam.ac.uk
# to redirect new longer friendly names to old short ugly names.
#
domainlist longshort_domains = cdb;DB/longshort.cdb
# ...
domain_longshort:
driver = redirect
domains = +longshort_domains
data = ${quote_local_part:$local_part}@${domain_data}
forbid_blackhole
forbid_file
forbid_include
forbid_pipe
check_ancestor
retry_use_local_part
