thanks for the hint but that's not possible in case of "contains" rules
where you don't know at which place the offeding phrase comes
interesting that we have around 1100 such rules and the
Spamassassin/ClamAV virtual machine runs most of the day between 50 and
300 MHz
In this case, aren't the first and last ".*" redundant anyway?
/.*need to buy products.*\?.*/i
is functionally equivalent to
/need to buy products.*\?/i
That, too. .* at the end of an RE is totally pointless.
