Thank you for your reply, Wietse, about this not being possible.
However, I am slightly confused about the documentation saying that
if..endif is allowed to nest. Does this mean that I could write
something like the following:
if /pattern/flags
if !/pattern/flags
endif
endif
If so, I would think I could write a nested if..endif that did what I
wanted. The first if..endif could check to see if the From/Return Path
matched our domain. If it did, wouldn't it then step into the internal
if..endif, where I could check to see if the message ID was ours? If
not, I could tell Postfix to then reject the message.
Or am I misunderstanding what is meant by "the if..endif can nest"?
Thanks,
Bryan
