Hello,
I want to find a keyword in the subject between two "*". How do I have to mask the "*" correctly?
I tried: if header :matches "subject" "\*xyz\**" if header :matches "subject" "\\*xyz\\**"

Use ":contains" instead of ":matches":
if header :contains "Subject" "*xyz*"
In ":contains", asterisks aren't wildcards and don't need escaping.

Thanks for the hint. But that means the keyword can be within the subject. I actually only wanted to look for it at the beginning.

Ah. In that case, you want:
if header :matches "Subject" "\\*xyz\\**"
I tested this and it works; see https://datatracker.ietf.org/doc/html/rfc5228#section-2.7.1:
"?" and "*" may be escaped as "\\?" and "\\*" in strings to match against themselves. The first backslash escapes the second backslash; together, they escape the "*". This is awkward, but it is commonplace in several programming languages that use globs and regular expressions.
