I know it may seem to be a newbye question but I really need an help
with system filter syntax.
I am trying to block some spam that uses typos to fool spamassassin.
At the moment, I have this regex expression in the ACL control
section of the configure file:
regex = [Vv] *[Ii] *[Aa] *[Gg] *[Rr] *[Aa]
This regex, however, blocks every combination of upper/lowercase
characters. What I need is a regex, or a system filter expression
that match every combination of characters in the specified word. To
make an example: i would like to be able to block words like VIAsGRA,
VIAGGRA, VijAGRA and so on.
How can I tell exim to consider the specified word and every possible
character between the very characters of the specified word?
I also have a list of words in the system filter, I regularly update
with new words but it is impossible to go on this way.
Thank you very much... and sorry if my question is stupid... I am not
so expert...
