I am running cyrus 2.0.9, which comes with timsieve ready to go. I can telnet to the timsieve port and get a list of sieve features that include "vacation" among 7 others. I install a sieve script like the following: require ["fileinto","vacation"]; vacation :days 7 :addresses ["[EMAIL PROTECTED]", "[EMAIL PROTECTED]"] "(Testing a new vacation script. Sorry!)"; But mail to this user doesn't elicit a response message. I know that the script is in the right place because I can get sieve to do other things for me, if I put an if and a "redirect" (e.g) in the file above. I generated vacation scripts by hand, and also through websieve. It has not worked in any case. Can you suggest something else I should try? Thanks in advance, Juan
