[Dovecot] filtering problem using sieve

[ajmcello ajmcello]

For some reason, I cannot filter messages that have uppercase or possibly
mixed casing in them. I have tried several tests by connecting
to port 25 and sending messages. The ones that fail are from
MAILER-DAEMON at mydomain.net. Here are the rules I have tried:


require ["fileinto", "reject", "vacation"];

if header :contains ["To", "Cc", "Bcc", "Reply-To", "In-Reply-To"] "
mailer-daemon at mydomain.net" {
        fileinto "mailer-daemon";
        stop;
}

if header :contains ["To", "Cc", "Bcc", "Reply-To", "In-Reply-To"] "
MAILER-DAEMON at mydomain.net" {
        fileinto "mailer-daemon";
        stop;
}

if header :contains ["To", "Cc", "Bcc", "Reply-To", "In-Reply-To"] "
MAILER-DAEMON at mail.mydomain.net" {
        fileinto "mailer-daemon";
        stop;
}

if header :contains ["To", "Cc", "Bcc", "Reply-To", "In-Reply-To"] "
mailer-daemon at mail.mydomain.net" {
        fileinto "mailer-daemon";
        stop;
}



They all fail to deliver to my mail folder "mailer-daemon" and go to my
inbox instead.

Anybody have any ideas what I am doing wrong? Also, how can I add a wildcard
so that I do not have to

specify subdomains?



Thank you!
