[Dovecot] SIS errors - was Error from mobile client (Palm Pre)
by Daniel L. Miller 04 Dec '10

Continuing to see errors on this with some new messages. Is it possible this has anything to do with zlib plugin, or possibly having a mix of zlib compressed & uncompressed messages with mdbox? I recently added zlib to deliver plugin list. -- Daniel L. Miller, VP - Engineering, SET AM Fire & Electronic Services, Inc. [AMFES] dmiller(a)amfes.com 702-312-5276

[Dovecot] v2.0.8 released
by Timo Sirainen 03 Dec '10

03 Dec '10

http://dovecot.org/releases/2.0/dovecot-2.0.8.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.8.tar.gz.sig There are many small fixes all around, plus some more noticeable changes: * Services' default vsz_limits weren't being enforced correctly in earlier v2.0 releases. Now that they are enforced, you might notice that the default limits are too low and you need to increase them. This problem will show up in logs as "out of memory" errors. See default_vsz_limit and service { vsz_limit } settings. * LMTP: In earlier versions if mail was delivered to user+detail@domain address, LMTP server always attempted to deliver the mail to mailbox named "detail". This was rather unintentional and shouldn't have been the default. lmtp_save_to_detail_mailbox=yes setting now preserves this behavior (default is no). + Added systemd support (configure --with-systemdsystemunitdir). Based on patch by Christophe Fergeau. + Replaced broken mbox-snarf plugin with a new more generic snarf plugin. - dbox: Fixes to handling external mail attachments - verbose_proctitle=yes didn't work for all processes in v2.0.7 - imap, pop3: When service { client_count } was larger than 1, the log messages didn't use the correct prefix. Last logged in user's prefix was always used, regardless of what user's session actually logged it. Now the proper log prefix is always used. - MySQL: Only the first specified host was ever used

[Dovecot] Indexes.
by Henrique Fernandes 03 Dec '10

03 Dec '10

Hello people! I have huge problems with IO wait becase dovecot configured to use maildir is under OCFS2 1.4. Now i have an question to OCFS2 each disk action is really heavy becaue it has no index. Now i am thinking in what can be done to heltp my system to use less disk. Looking for index and etc in dovecot i found this, this disables the index file on disk and leave it on ram or it disable the index files ? If you really want to, you can also disable the index files completely by appending :INDEX=MEMORY I am only trying to get dovecot to work faster. Right now we have to waing some seconds to dovecot list all emails or read an email. I am also thinking in right index to an NFS but i don't know if this makes any diferences in performance. Thanks to all! I use 3 servres wrinting on OCFS2 one is mailman, and other two are to email, I have ipvs to load balance the conections. []'sf.rique

[Dovecot] Dovecot lmtp
by Benedetto Vassallo 03 Dec '10

03 Dec '10

Hello to all, I am setting up a mail server using sendmail and dovecot 2.0.7 with maildir storage. I want to use dovecot lmtp as local mail delivery agent becouse when I send a message to multiple recipients it deliver the message to all recipients with hard links instead of store n copies of the message. The only think I can't set up is make dovecot-lmtp reading the .forward file in the user's home directory. I think I am missing something, becouse dovecot-lda read that file but don't do hard links when deliver the mail. What I am missing?

[Dovecot] SSL issues on separate IPs
by Tim Traver 03 Dec '10

03 Dec '10

Hi Timo, I have set up 2.07 to answer on several different IP's with different SSL certs, like the following : local 209.132.xx.4 { ssl_cert = </shared/templates/res/1040/certs/*.xxxxx.com.crt-pem-298 ssl_key = </shared/templates/res/1040/certs/*.xxxxx.com.key-298 } I have several of these, and there appears to be a problem with one in particular that is dropping connections, and I'm not sure why. In this case it is a wildcard cert issued from godaddy, and I have the cert file in pem format with the chain on it. I have another completely separate local IP setup with a different cert on it that works without any problems. This particular one drops the connection when I try to connect to IMAP using TLS on port 143, or using the IMAP SSL port of 993. When I try it using Thunderbird, I am using the default settings for both tests. The Thunderbird error I get is "The server has disconnected. The server may have gone down or there may be a network problem." I don't see any errors in the dovecot error log or the system error log, and when using doveadm who to view the current connections, it does not show a connection. I tried enabling the logs for SSL errors, but nothing appears for my IP when attempting to connect. FreeBSD 8.1 with openssl 0.9.8n. The IP's are on the box and are on the loopback interface if that makes any difference for a direct server return load balancing system. But, I don't know how that would make a difference since one of the separated IP's works with its cert, and the other one disconnects. Thanks, Tim.

[Dovecot] Static userdb with LDAP passdb but without "allow_all_users=yes"?
by Andreas Ntaflos 03 Dec '10

03 Dec '10

Hi, Is it possible to have a static user database along with an LDAP password database and *not* be forced to set "allow_all_users=yes" for the userdb? The wiki page on static user database says "Normally static userdb handles this by doing a passdb lookup instead." How should the passdb behave in order for this to work? In my tests (on a test server) I am using Dovecot 2.0.7 and Postfix 2.7.0 on Ubuntu 10.04.1. I use (or am trying to use) LMTP with Dovecot and Postfix according to the HOWTO in the wiki [1] as well as dynamic address verification with LMTP [2]. Users are virtual, using a static userdb and passwords from LDAP. I also serve local system users which is why I also have userdb and passdb pam, but this isn't the issue here. Delivering mail to an existing virtual user works fine as far as I can see but when a non-existent user is the recipient Dovecot complains that the passdb doesn't support lookups: postfix/smtpd[26469]: connect from remote-smtp.example.net[10.0.0.10] postfix/cleanup[26474]: 772A760B25: message- id=<20101125172409.772A760B25(a)mailtest.example.com> postfix/qmgr[27672]: 772A760B25: from=<double- bounce(a)mailtest.example.com>, size=276, nrcpt=1 (queue active) dovecot: lmtp(22109): Connect from local dovecot: auth: Error: static(not-a-user(a)test01.example.com): passdb doesn't support lookups, can't verify user's existence dovecot: lmtp(22109): Error: user not-a-user(a)test01.example.com: Auth USER lookup failed dovecot: lmtp(22109): Disconnect from local: Client quit postfix/lmtp[26475]: 772A760B25: to=<not-a-user(a)test01.example.com>, relay=mailtest.example.com[private/dovecot-lmtp], delay=0.18, delays=0.17/0.01/0/0, dsn=4.3.0, status=undeliverable (host mailtest.example.com[private/dovecot-lmtp] said: 451 4.3.0 <not-a- user(a)test01.example.com> Internal error occurred.

I can also provide a log excerpt from a successful delivery to an existing virtual user, if needed. To summarise: I want to use LMTP, dynamic address verification, a static user database and an LDAP password database. Can it be done without having to rely on the MTA (Postfix) to verify existing users? Thanks in advance!
