I did not test that, I would imagine that should work because how would
it really know what return values you are sending back.
I know that using sg{} or {if match {} {} {}} does not work, string
expansion fails...
Even this fails...
${if match {$local_part}{.*sms[\-\+]([a-z0-9]+).*}{$1}{}}
With expansion failure due to tainted... I'm clearly just pulling how
known safe data, so it should be considered de-tainted....
There is literally no difference vs doing some fake lookup...
