I did a lot of work on this early on this year and there was extensive
discussion so you may want to search the archives.
In current versions of IMAIL you can manipulate this file from the
IMAIL Monitor Web Interface (normally port 8181). However, it does
not do a reverse dns lookup.
I wrote my own programs for manipulating this file. Here is the file
layout I used. There is no documentation from IMAIL and obviously it
might change at any time. However, my programs are working using this
format with no IMAIL problems so far.
byte: 000 - 00B unknown
byte: 00C on/off indicator deny or permit
byte: 00D - 00F unknown
byte: 010 - 013 length of combined arrays (big endian)
byte: 014 begin array:
xx xx xx xx mm mm mm mm
where xx is 4 bytes for IP addreess
mm is 4 bytes for mask
you double this to get the
counter in 010-013
array ends with "0 0 0 0 FF FF FF FF"
and deleted entries may appear after this
marker
There may be an end marker, too.
markers are included in the array lengths.
Inserts should occur at the first marker.
The array is read into memory by IMAIL so changes have to be followed
by an SMTP toggle.
