Consider these mail headers:
X-Spam-Level: ***
X-Spam-Status: Yes, score=3.7 required=3.0 tests= (remaining truncated for brevity)
I simply want to match the headers
"X-Spam-Level: ***" (at least with more "*" okay)
or
"X-Spam-Status: Yes, score=3.7" (or a higher score)
I have this, which matches the X-Spam-Level header, but I'm seeing stuff slip through with a score of 3.7 or higher, making me believe the alternation is being skipped:
:0 H
* ^X-Spam-Status: Yes
* ^(X-Spam-Level: \*\*\*\*)|(^X-Spam-Status: Yes, score=3\.[7-9])
{
do stuff
}
Procmail's regex implementation is just not quite the same as what I'm used to and can't get this to work, despite matching on sites like regex101.com
I'm perfectly fine with a solution just matching the score of 3.7 or higher and removing the X-Spam-Level condition completely.
Note: I am aware that the minimum score I've set in Spamassassin is 3.0 to flag as spam, however, I deliver stuff to the user's mailbox between 3 and 3.6 and move anything higher to a server spam mailbox. Presently, it's only getting delivered to the server's spam mailbox if 4.1 or higher, as denoted by the asterisks in X-Spam-Level.

I never could get this working. Instead, I modified the Spamassassin local.cf config to add a header line:
add_header all Score _SCORE_
This creates a new mail header of X-Spam-Score: n.n where n are digits.
In the procmailrc file, I added this line to the top:
# Change this value to be whatever threshold
# you want
# Spam scored between 3 and 3.6 will be delivered.
# Spam scored over 3.6 won't.
SPAMTHRESHOLD=3.6
Later in the file, after spamc is called, I declare a variable to capture the score then check against it:
# Create SCORE variable which contains the header I created in Spamassassin
:0 # H flag is implicit
* ^X-Spam-Score: \/.+
{ SCORE=$MATCH }
# Check for Spam-Status: Yes, and
# $SCORE > $SPAMTHRESHOLD
:0 H
* ^X-Spam-Status: Yes
* $ -${SPAMTHRESHOLD}^0
* $ ${SCORE}^0
{
# do stuff. in this case move the mail to
# /var/mail/spam
:0:spam.lock
/var/mail/spam
}
