20 | /* When a router wants to change the address that is being routed, it is like a | |
21 | redirection. We insert a new parent of the current address to hold the original | |
22 | information, and change the data in the original address, which is now the | |
23 | child. The child address is put onto the addr_new chain. Pick up the local part | |
24 | from the "address" field so as to get it in external form - caseful, and with | |
25 | any quoting retained. | |
26 | ||
27 | Arguments: | |
28 | addr the address block | |
29 | domain the new domain | |
30 | rewrite TRUE if headers lines are to be rewritten | |
31 | addr_new the new address chain | |
