[exim] optimizing a condition

Hi,

does anyone see a way to optimize one condition away without changing
the SQL ?

          condition = ${if !eq{TXTA}{${lookup mysql {SELECT --SQL-- }}} {1}}
          condition = ${if !eq{TXTB}{${lookup mysql {SELECT --SQL-- }}} {1}}

Note: both SQL call exactly the same.

would this be possible, it would help

    set acl_m9 = ${lookup mysql {SELECT --SQL-- }}
    condition = ${if !eq{TXTA}{$acl_m9} {1}}
    condition = ${if !eq{TXTB}{$acl_m9} {1}}

Also an option would be something like this : any REGEX available at
that point?

    condition = ${if !Regexp{(TXTA|TXTB)}{ SQL } {1}}

best regards,
Marius
