Do NOT use ".*" in body or rawbody rules. That can lead to unbounded
processing times. Use a sane upper limit, e.g. ".{,20}", and try to
avoid repeated "." where possible
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
And since you don't need (or want) too much extra stuff before the
question mark, you could easily limit it without losing functionality.
/need to buy products.{,20}\?/i
