This does not look OK.  If we trace how @initial_to gets its value,

 - it first gets its value from @getopt_to and @config_to

 - if that is empty, and there is no $to_cmd, the end-user is
   interactively asked.

 - then process_address_list() is applied.

But this patch just swapped the second one and the third one, so
process_address_list() does not process what the end-user gave
interactively, no?

It almost feels like what need to move is not the setting of these
address lists, but the code that calls int validation callchain that
needs access to these address lists---the block that begins with the
above "if ($validate) {" needs to move below ...

... this point, or something, perhaps?
