Map realm to user
Hi, I have a postfix/cyrus/sasl mail server authenticating against an ldap server. It all works fine using a 'login:password' authentication but I would also like to user 'login@realm:password' authentication for the mail accounts (imap and pop3). The authentication bit work fine when I use 'login@realm' (in imap) but no mailbox is opened... Well my question is: is it possible to map 'login' and 'login@realm' to the same mailbox? and if so how can I do that? Thanks Pedro Silva > Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
Re: Map realm to user
Thanks for the suggestion. I tried what you said bust the result was the same... Here is what my logfile looks like using a webmail imap client When I authenticate with 'user:pass' cyrus/imap[24503]: accepted connection cyrus/imap[24503]: login: servername [x.x.x.x] 'user' plaintext User logged in cyrus/imap[24503]: open: user 'user' opened INBOX now when I use 'user@domain:pass' cyrus/imap[24572]: accepted connection cyrus/imap[24572]: login: servername [x.x.x.x] 'user@domain' plaintext User logged in but no inbox is opened and no error is reported.

Cyrus (Sieve) and external programs
Hello, I'm trying to set up a spam learning system, and I would like to pipe email places in (for example) the SPAM folder to an external program. I have cyrus 2.4.17 Does any one know how or if this is possible in cyrus (or sieve)? I wasn't able to find any documentation about using external programs with sieve.

Re: Cyrus (Sieve) and external programs
Hello Sven, Thanks for your answer. Actually I would like to set up a system were a user would move his messages to a spam folder, and by doing so, the message would be sent to the spam learning system. Ive seen something like this in other distributions (eg.: https://wiki.dovecot.org/HowTo/AntispamWithSieve) I was just wondering if the same is possible with cyrus or cyrus sieve.

Hei Adam, Thanks. This is a great starting point. I'll try to get it to work with my setup. Again, thanks.

Re: Cyrus (Sieve) and external programs
Niels,
sa-learn would be the way to go, but my spamassassin is not on the same
server as my mailboxes. I tried solution with a common mailbox and
something like fetchmail on my spamassassin machine, but could not get
it to work as I intended.
You are right about learning based on user experience, but as it is a
score based learning I would like to try to see how it goes. Maybe I'll
come to regret it but well...
Best regards,
Pedro Silva
