This variant leads to the same error "421 Unexpected failure" and similar
records in panic log.
However, running "exim -brw" displays anomaly:
if lookup succeeds then output is correct (with substitution from map-file),
if lookup does not succeed exim says:
2020-01-13 21:58:56.367 [171495] Rewrite of evgeniy_berdni...@xxx.msk.ru
yielded unqualified address "evgeniy.berdnikov"
to: evgeniy_berdni...@xxx.msk.ru
I lead to conclusion that variables $0, $1, etc are not visible inside ${sg}.
Suprising. My experiments with "exim -be" show that those variables are
passed clean from 'match' to ${sg}, for example:
-- try $0:
exim4 -be '${if match{aa__bb}{a+(_+)b+}{${sg{$0}{_}{.}}}{NONE}}'
aa..bb
-- try $1:
exim4 -be '${if match{aa__bb}{a+(_+)b+}{${sg{$1}{_}{.}}}{NONE}}'
..
Probably there is some specific for rewriting which I do not understand.
