Sorry, there were _two_ typos.
- ":header" should be "header", as you pointed out
- "Yes*" should be "Yes.*"
The last one is the key one. I tried:
if header :matches "X-Spam-Status" "Yes.*"
{ fileinto "INBOX.Junk"; }
else
{ keep; }
Everything went into Inbox. However, this works:
if header :matches "X-Spam-Status" "Yes*"
{ fileinto "INBOX.Junk"; }
else
{ keep; }
The problem is that the regular expression "Yes*" matches "Ye" followed
by 0 or more "s"s. So, case sensitivity aside, if the following line
was in the mail:
X-Spam-Status: No (score=1.2): LINES_OF_YELLING=1.2
^^
the message would incorrectly be dumped into the Junk folder.
Using Cyrus sieve filters, the line:
if header :matches "X-Spam-Status" "Yes.*"
works as expected.
This is on a friend's machine, running Exim 4.20.
