[Dovecot] dsync: mbox to maildir hangs
by Burckhard Schmidt 13 Sep '10

13 Sep '10

Hello, after successfully converting some mailboxes I have a problem: dsync does not finish its work. dovecot 2.0.2. mail-location maildir:~/maildir I have copied the old Inbox and folders into /mailstore1/import-inbox and /mailstore1/import-home to the new server. (used with Dovecot 1.0.13 before) For one account I have now 356 folders containing about 60000 emails. (35 folders with about 40000 emails had been converted without problems) I used: dsync -v -u account mirror mbox:/mailstore1/import-home/~account:INBOX=/mailstore1/import-inbox/account dsync shoes after two minutes a list of all folders like this dsync(account): Info: Mail/folderx: only in dest After about 8 minutes some folders are converted. But then it hangs inside a folder which is just converting. I see entries (emails) inside "folder/tmp" but not all. And the "folder/cur" is still empty. dsync uses about 75% of one cpu all the time. I was waiting more than 50 minutes but no progress. I have to use kill -9 to stop it. If I delete this folder it still happens with a different one. Are there any limitations? Any advice? Regards - Burckhard Schmidt

[Dovecot] Pigeonhole proxy errors
by Cassidy Larson 13 Sep '10

13 Sep '10

I'm trying to upgrade my proxy front-ends to 2.0.2. I have the latest Pigeonhole release installed, and whenever I connect to the sieve port this gets logged in the syslog: managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=144(<unknown>) egid=144(<unknown>) missing +x perm: /, euid is not dir owner) I dont get any capabilities displayed on the client side. I'm not sure why it's referring to the '/' directory. On 1.2.x, I authenticate the user and proxy to the sieve process on appropriate users back-end storage node. Here is the sieve config in my dovecot config file: ------------ service managesieve-login { inet_listener sieve { address = a.b.c.d port = 4190 } inet_listener sieve_deprecated { address = a.b.c.d port = 2000 } } protocol sieve { managesieve_max_line_length = 65536 managesieve_logout_format = bytes=%i/%o managesieve_implementation_string = Dovecot Pigeonhole mail_debug=no } -------- Any help would be great. thanks!

[Dovecot] dovecot 2.0.2 compile issues on Solaris 10u8 Sparc
by Jerry K 13 Sep '10

13 Sep '10

I am having compile problems with Dovecot v2.0.2 on a well patched Solaris 10u8 Sparc system using the included gcc compiler. Version 2.0.0 compiled with out any issues using the same configure syntax. My ./configure syntax looks like this: ./configure --with-ssl=openssl --with-shadow Yahoo and Google searches turned up nothing for me. Reviewing the file mountpoint.c between version 2.0.0 and 2.0.2 shows the files to be identical, so I have a problem somewhere else, I am just not sure where.

[Dovecot] LMTP proxying strategy with multiple recipient delivery
by Luca Palazzo 13 Sep '10

13 Sep '10

Hi Timo and All, how does Dovecot act when an MTA tries to deliver a multiple recipient message to a LMTP proxied system? Does it uses server affinity table for each recipient? I use lmtp_destination_recipient_limit = 1 setting in postfix to avoid multiple recipient delivery. Is it right? I use lmtp_destination_concurrency_limit = 1 too, but i think that it's useless or, maybe, it can make performance worst. Luca

Re: [Dovecot] Upgraded dovecot - now it insists on imap TLS
by Alan Brown 13 Sep '10

13 Sep '10

Marcus Rueckert wrote: > > What am I missing? > dovecot -n output would help. It would, but I found/fixed the problem already. I had to set the following: protocol imap { disable_plaintext_auth=no } The default has changed from "no" to "yes" between 1.1.20 and 2.0.1, but the conversion routine didn't pick it up (the wiki Documentation suggests the default is still "no". Perhaps this should be updated?) This still requires TLS on port 993, so there's no additional hole opened. Ironically, we published plans some time back to disable local-access plaintext imap logins in October and have been warning users to change their settings but 90% of them hadn't yet done so.

[Dovecot] Dovecot 2.0.2 breakes LMTP delivery for me
by Fabian Ruff 13 Sep '10

13 Sep '10

Hi, I'm onboard Debian Lenny (amd64) and just reverted from 2.0.2-0~auto+4 back to 2.0.1-0~auto+1 because LMTP stopped working completly with the above Package. In my setup delivery is done from exim via LMTP to dovecot (Maildir/ext3). The lmtp dovecot config looks like this: > service lmtp { > user = vmail > inet_listener lmtp { > address = 127.0.0.1 > port = 24 > } > > unix_listener lmtp { > } > } > protocol lmtp { > hostname = [...].de > mail_plugins = sieve quota listescape > postmaster_address = postmaster@[...].de > } With the new version I get no LMTP log message at all from dovecot and Exim fails with: > LMTP timeout after initial connection When I do "/etc/init.d/dovecot stop" some process remain alive and I ultimately have to SIGKILL the lmtp process to get rid of it. > trench:/tmp# ps auwx |grep dovecot > root 2643 0.0 0.0 8224 768 pts/1 R+ 22:50 0:00 grep dovecot > root 31778 0.0 0.0 12384 684 pts/2 S+ 22:36 0:00 tail -f > /var/log/mail/dovecot.log > dovecot 32368 0.0 0.0 12656 996 ?
