Regular expression for spamassassin

[David Baron <d_baron@012.net.il>]

I entered using webmin. Trying "evaluate" kicks at the regex. The syntax, 
which it wants enclosed /regex/ (like in PERL), seems correct. The spam 
detection using it actually worked. A "grep invalid regex" error gets sent 
from the next logcheck, however.

Anybody know how to correct this behavior?

The rules are of the form:
/v[i1*]agra/i
/c[i1*]al[i1*]s/i
 ( it did not like the fully specified [Vv]... form without the 'i" directive 
either.)

We all know why :-)
