I have now solved this issue by rewriting the aliases through an LDAP
lookup on the MTA on the RT server. In this case, Postfix.

main.cf:
  local_header_rewrite_clients = hash:/etc/postfix/smtpservers
  sender_canonical_maps = ldap:/etc/postfix/canonical-ldap.cf

canonical-ldap.cf:
  server_host = ldap.example.com
  version = 3
  search_base = o=example.com
  query_filter = mailalternateaddress=%s
  result_attribute = mail
  domains = example.com
