Hi there, I have had no response to this message I have posted a week back so I'm giving it another bash. I have recently installed and configured cyrus-imapd-1.6.24 to run on a HP 9000 (HP-UX 10.20) All is working well and I'd now like to enhance the setup through the implimentation of sieve filters. I'm having problems with sieve authentication when I try to list or add filters. I'm using the unix password file for imap authentication. From the archives it would appear that the sieve authentication is a known bug for which no fix exist (yet?) under release 1.6.24 sasl_pwcheck_method: passwd Here is the command I use to try and add a filter: installsieve -i filter -m passwd -u hennie localhost I get the following error without being prompted for a password: Authentication failed. Is this a known bug ? Anyone using this feature under this release ? Is there a fix available ? Please help ! Regards, Hennie
