Right, "smart.ru" matches "rt.ru" after the "sma".
Perhaps:
${if match{$sender_host_name}{\N(?:^|\.)\N${sg{$acl_m55}{\N\.\N}{\N\\.\N}}\N$\N}}
is what you want?
It used to be that match_domain gave you what you wanted, but this
proved to be too vulnerable to insecure configurations being created, so
we stopped expanding the right-hand-side. :-(
The above ${sg...} assumes that the results of the database lookup can
only match legitimate Internet domain-names, so the "." is the only
regexp special character that can occur.

The $sender_host_name should not have $$ doubled, you're causing an
expansion failure there.
Is the above what you wanted, or have I misunderstood?
