Needing the translation in the headers rather than the envelope
makes things a bit more complicated. The easiest approach might
be to modify resend to check a new header instead of, or in addition
to, the To: field. (E.g. X-Course-Codes:) Then use a traditional
alias file with entries of the form:
elec-year1: class-5B7U+2RNU+3KAU@???
elec-year2: class-777V+2RCV+3KDV@???
and an Exim director along the following lines:
class_lists:
driver = smartuser
domains = "gla.ac.uk"
prefix = "class-"
new_address = "class@???"
headers_add = "X-Course-Codes: ${local_parts}"
