118 makes it easy to read back into a tree. The format is as follows:
120 . Each node is preceded by two letter(Y/N) indicating whether it has left
121 or right children. There's one space after the two flags, before the name.
123 . The left subtree (if any) then follows, then the right subtree (if any).
125 This function is entered with the next input line in the buffer. Note we must
126 save the right flag before recursing with the same buffer.
128 Once the tree is read, we re-construct the balance fields by scanning the tree.

612 Since an address must end with a domain, we can tell that extra data is
613 present by the presence of the terminator, which is always some character
614 that cannot exist in a domain. (If I'd thought of the need for additional
615 data early on, I'd have put it at the start, with the address at the end. As
616 it is, we have to operate backwards. Addresses are permitted to contain
619 This code has to cope with various versions of this data that have evolved
620 over time. In all cases, the line might just contain an address, with no
621 additional data. Otherwise, the possibilities are as follows:
623 Exim 3 type: <address><space><digits>,<digits>,<digits>
625 The second set of digits is the parent number for one_time addresses. The
626 other values were remnants of earlier experiments that were abandoned.
628 Exim 4 first type: <address><space><digits>
630 The digits are the parent number for one_time addresses.
632 Exim 4 new type: <address><space><data>#<type bits>
634 The type bits indicate what the contents of the data are.
636 Bit 01 indicates that, reading from right to left, the data
637 ends with <errors_to address><space><len>,<pno> where pno is
638 the parent number for one_time addresses, and len is the length
639 of the errors_to address (zero meaning none).
