[Dovecot] sieve filtering, rewriting subjects
by Ian P. Christian 26 Oct '07

26 Oct '07

Is it possible to modify an emails subject line in a sieve script? I've seen references to 'addtag' whilst googling, but it appears dovecots implementation doens't support it - are there any other methods? As a side note, can anyone suggest a web based script editor that works? Simply a text area to write the script in would do Thanks, -- Ian P. Christian ~ pookey.co.uk

[Dovecot] SSL help needed - "no root certificate"
by Jim Gottlieb 26 Oct '07

26 Oct '07

Hi. I've spent the past few hours trying to get SSL working right in Dovecot 1.0.5 and now I must turn to you for help. I purchased an SSL certificate from Go Daddy. I pointed ssl_cert_file to the .crt file and ssl_key_file to the .key file, but the client (Mail.app) complains: Mail was unable to verify the identity of this server, which has a certificate issued to "imap.nccom.com". The error was: There is no root certificate for this server. So I tried downloading Go Daddy's root certificate and pointing ssl_ca_file to that file, but that didn't help. So I tried pointing ssl_ca_file to the intermediate certificate sent to me by Go Daddy, but that breaks things to the point where I never even get the above message; just nothing happens at all. I'm not sure what to try next and am happy to entertain any suggestions. Thanks...

[Dovecot] Dovecot crashing with "Status userdb: Empty key (=)"

[Dovecot] SSL/TLS with Outlook client
by Eli 25 Oct '07

25 Oct '07

I am trying to get TLS to work with Outlook 2007 and I've hit a small problem. Whenever I start it up, I get this error: "The server you are connected to is using a security certificate that cannot be verified. The target principal name is incorrect." (yes/no choice of trusting) I first tried with a wildcard cert (*.elisand.com), and then tried with mail.elisand.com - both certs are from cacert.org and the root CA certs are installed and functioning properly on my system (so the certs should be trusted). I've searched all over Google and such trying to find out why Outlook would give me this error from an IMAP/TLS connection (closest I could find was Exchange related info), and I know this is by no means an Outlook mailing list... though I'm just wondering if anyone else on here has ever encountered this problem before and could point me in the right direction to getting the SSL cert working with Outlook. Thanks in advance!

[Dovecot] POP3/IMAP newbie question
by Lars Stavholm 24 Oct '07

Is it possible to serve both POP3 and IMAP for the same user from the same mailbox format, e.g. the maildir format? If so, how should I configure in dovecot.conf?

[Dovecot] How to debug slow operation
by zbigniew szalbot 24 Oct '07

24 Oct '07

Hello, I am no programmer at all. I have dovecot set up on two very similar machines. On one of the boxes, the dovecot server has recently been showing slower response times. It feels slower. Where it is slower, dovecot works as an auth server for postfix. I have replaced exim with postfix on that box and I think since then dovecot started to slow down. On the other machine the MTA is exim. I'd like to ask how to go about debugging the problem. Neither machine serves many users, the one that is slower has currently only two. It's a home setup really. Here's the output of dovecot -n # 1.0.5: /usr/local/etc/dovecot.conf protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: Server ready. verbose_proctitle: yes first_valid_uid: 125 first_valid_gid: 125 mail_extra_groups: mail mail_location: maildir:/usr/local/virtual/%d/%n mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login passdb: driver: sql args: /usr/local/etc/dovecot-postfix-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-postfix-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 384 user: postfix group: postfix Many thanks for your suggestions!

[Dovecot] graceful failure when some folders are not available...
by bhayden＠umn.edu 23 Oct '07

23 Oct '07

Hi folks. Quick question in the hopes that someone knows the answer, before I dig in the code some more. In testing a new setup with some long-term archival mbox-format mailboxes stored on an NFS mount, we've found the following: if the mount is unavailable for any reason, the user cannot log into their email at all. Dovecot says: "stat() failed with mbox foo" and dies. This is coming from the mbox sync checks. (It's possible the same happens with a maildir folder--I'm just specifying mbox because that's what we've tested with so far). Is there a way to reconfigure this behavior? I could maybe see a fatal abort if the inbox is unavailable, but for other folders it seems rather... presumptuous. I have to think there's already a way to handle this more gracefully in the config and I'm just not seeing it. Also, does anyone know offhand if this behavior is the same for folders that aren't in the default/inbox namespace? That would seem *really* wrong. Any thoughts? Thanks much, -Brian

This message that I just sent did the error which was a reply. But, a new message I created earlier today after installing Beta 4 worked fine. Maybe it has something to do with replies versus new messages. Jeff
