[AMaViS-user] Spamassassin rules and escape characters.

[Benedict White]

I posted this in a spam assassin group which seems little used and wondered if anyone here could help:

I have started to write my own custom rules to deal with rubbish like
that below.

I am looking at writing meta rules, which seems fine and gets a few
hits, but what I need to know is what punctuation marks and characters
need to be escaped. I know that $ and . would need to be \$ and \. to
be literal, but what about things like :,' or"?

Example:

olesia_k "Let Talk About Love"

Try that one.

Either way, your question isn't a spamassassin or amavisd-new question.
It is a perl regular expression question.

For examples, cd to your spamassassin rules directory and look at examples,
or google for perl regular expressions or us perldoc or man perl.

The question belongs to us...@spamassassin.apache.org mailing list.

See: man perlre

Typically what needs to be quoted are: . ? + * | ( ) [ ] { } ^ $ \ @
and a character which is used as a regexp delimiter, often a /

To avoid having to quote a /, instead of:
uri L_LUST /^http:\/\/www\.(need|crave)-lust\.com(\/|$)/i
one could use:
uri L_LUST m{^http://www\.(need|crave)-lust\.com(/|$)}i

See: man perlop, look for operator m//
