Hi,

"header :is From" compares against the whole From: header. You only
want to test the containing email address. See

address This lets you match on only an address field's email address, not its
associated name. For example, I could send an email as "John Smith" <jsmith@example.com

. The test header "From" :is "jsmith@example.com" would be false
because that is not the entire header. But address "From" :is "jsmith@example.com " would be true because that is the entire address.

Check the RFC and search for "address", there you will find
explanations and examples http://www.faqs.org/rfcs/rfc3028.html

I have a problem with a sieve script.. my config is dovecot 1.2.15 with managesieve, and roundcube. if anyof (header :contains "From" "xxx@example.com") if anyof (header :is "From" "trac@ardeek.com")

":is" is an absolute match, ":contains" is a substring match.

http://tools.ietf.org/html/rfc5228#section-2.7.1

Of course, but with the SAME header "From:" ( From: "AA" <xxx@sample.com

...

for example) :contains match but :is _don't_ match... i don't understand the reason :/

For my logic "if anyof (header :is "From" "xxx@example.com")" should
match "From: "AA" <xxx@example.com>", but in practice that script
don't.
