The suffix is in the $local_part_suffix variable and contains
separator already (eg. +tag). I use this:

    dovecot_ualias:
      ...
      domains = +our_domains


      local_part_suffix = +*
      local_part_suffix_optional
      qualify_preserve_domain
      data = ${lookup{$local_part} lsearch{VMAIL_DOM_DIR/$domain_data/aliases} \
             {${quote_local_part:$value$local_part_suffix}} }


I have per domain alias file with data without RHS part, thus lookup
returns only local_part, to which is suffix appended.

If your lookup returns qualified addresses, try something as this with
lookup's result (not tested):

    ${sg{$value}{\N(@[^@]+)$\N}{$local_part_suffix\$1}}


regards
