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:[EMAIL PROTECTED] forbid_blackhole forbid_file forbid_include forbid_pipe check_ancestor retry_use_local_part Tony. -- <[EMAIL PROTECTED]> <[EMAIL PROTECTED]> http://dotat.at/ ${sg{\N${sg{\ N\}{([^N]*)(.)(.)(.*)}{\$1\$3\$2\$1\$3\n\$2\$3\$4\$3\n\$3\$2\$4}}\ \N}{([^N]*)(.)(.)(.*)}{\$1\$3\$2\$1\$3\n\$2\$3\$4\$3\n\$3\$2\$4}} -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
