[Dovecot] ManageSIEVE services with Dovecot cvs-LDA?
by OpenMacNews 28 Sep '05

28 Sep '05

hi all, has anyone had any success in getting the current dovecot cvs-lda's implementation of CyrusSIEVE responding to a ManageSIEVE client? in particular, i'm hoping that one can use, e.g., Mulberry's Client- & Server-side sieve editor: <http://www.cyrusoft.com/sieve/sievescreens.html> if i telnet to my dovecot box's sieve port ( = 2000) i get no response at all ... telnet localhost 2000 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host net-stat shows nothing on port 2000, and, afaik, there's no mention of a server on the wiki ... so i'm either doing something wrong, or "it" is simply not there. has a sieve server been implemented? any plans? thx! richard

[Dovecot] Dovecot Error: Master requested auth for nonexisting client
by Paul E Virgo 27 Sep '05

27 Sep '05

Hello, The subject line says it all. It seems to be happening with regards to my default auth setting in the dovecot.conf file. I currently have it set to 'plain'. Am I missing something? FWIW, I am using the latest, stable (alpha) release: 1.0.alpha3 PE Virgo

[Dovecot] mail not found
by Michael Collins 27 Sep '05

27 Sep '05

This is in my dovecot.conf default_mail_env = maildir:/var/mail/vhosts/%1u/%u/ my mail ia in/var/mail/vhosts/anawebdesigns.com/user1/cur, new, tmp As you can guess these are virtual accounts. Auth works but mail is not found. How do I need to modify the line in dovecot.conf? Thanks. -- -- Michael H. Collins It's us against them. Ride like you stole it. If you love some code, set it free.

But I found that I must add the mail=mbox:/var/spool/virtual/%d/%n part. Without this part, the dovecot seems not checking the right location of mail spool and simply say that "no new email". Now I added this part together with "home=/tmp" part into userdb config and It works now with IMAP folder in /tmp directory. But I want to ask if there is any file locking problem as I am running virtual email with vmail as owner for all mbox accounts. And it seems that they are all share the same IMAP folder located in /tmp directory.

[Dovecot] Hostname passed to PAM as rhost
by Tom Alsberg 27 Sep '05

27 Sep '05

(I am sorry to bother the list with something I should have verified myself right now - I simply do not have access to the source code here) Thinking of some limit I wanted to put with authentication, I am wondering - when Dovecot authenticates a user using PAM, now that (in 1.0) it passes the rhost item to PAM, it passes a hostname, not an IP address. Does it double-verify the DNS record before it trusts this to be the hostname (first checking the IP address in in_addr.arpa and then checking that the hostname indeed maps back to the same IP address)? That is necessary in order to trust the client address when determining authentication strength in the PAM module based on the client location (specifically we want stronger authentication when the client comes outside of our network, while inside a plain password suffices), as else anybody could "spoof" the hostname by changing the IN PTR record of his IP address to point back to some "trusted" hostname (given he has control of the DNS zone his host is in, which is completely possible given the server knows nothing about it).

[Dovecot] POP3 problem
by michal 27 Sep '05

27 Sep '05

Hey all this is my first post to this list. I have fresh Red Hat AS 4.0 with postfix 2.1. This will be my mail server. I have one problem with pop3. My mail server is working properly. I did the following test: Sent an email to some other server(yahoo.com)->email got there fine. >From that other server(yahoo.com) replaied-> to the new server and email got there fine,checked using pine. Now in x windows on the mail server if i lunch email client software and set up the account, then i can send and receive emails fine so pop3 is working. But when i go to different machine like PC set up outlook then i cannot receive emails. I get error in outlook that the connection has failed. So i telnet 192.168.1.10 110 and I have gotten response from the server 250 dovecot OK. I really dont what to do at this time. I have been trying couple different things without any luck..... need some help? Mike

[Dovecot] How safe is mbox_very_dirty_syncs?
by Chris Wakelin 27 Sep '05

27 Sep '05

I've tried turning on mbox_very_dirty_syncs for myself (and a few other brave souls running 1.0-alpha3 rather than 1.0-stable) again to see what perfomance gain it gives (see thread http://www.dovecot.org/list/dovecot/2005-July/007956.html). Now we aren't running UW-IMAP at all, how safe is mbox_very_dirty_syncs assuming the only other process writing to mailboxes is our MTA (exim) which simply appends messages to the end? Is it safer still using Dovecot 1.0-alphas and the LDA? Does it matter if there are concurrent connections to the mailbox?
