[Dovecot] 1.2.10 and questions
Hi, 1) Why dovecot -n doesn't display default values? At least it didn't display mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(pop3): 10 if I had set ONLY mail_max_userip_connections (to be =10) 2) Maximum number of connections from user+IP exceeded (mail_max_userip_connections): Could it be enhanced to actually log what the limit was at that time? -- Arkadiusz MiśkiewiczPLD/Linux Team arekm / maven.plhttp://ftp.pld-linux.org/

[Dovecot] Using a ramdisk but Timeout while waiting for lock for transaction log file
Hello, Dovecot 1.2.5, centos 5.4. We are using NFS for mail, but indexes are local and on a ramdisk. However I'm getting logs such as: Mar 02 11:47:14 POP3(USERDELETED): Error: Timeout while waiting for lock for transaction log file /ramdisk/indexes/DOMAINDELETED/USERDELETED/.INBOX/dovecot.index.log Our NFS is rather busy, and we having other warnings to that affect, but wouldn't have though we'd get timeouts on a ramdisk. -- Andrew

Hello,
i am trying to proxy a LMTP connection with version 2.0b3
Currently i have the problem when trying to use a named based proxy for
LMTP the process doesn't resolve the hostname and crashes:
Fixed crash and added DNS support:
http://hg.dovecot.org/dovecot-2.0/rev/bd28e6f29711
http://hg.dovecot.org/dovecot-2.0/rev/cc3f6adc1e0b
Thank you Timo, it is working now.
But unfortunately i ran into a second problem which was already existent
before the DNS fix.
When the LMTP client sends the terminating dot to the LMTP proxy, the
proxy stalls for about 30sec at an epoll_wait() syscall.
It reads the 250 2.0.0 x response from the backend server and then
waits.
When the epoll_wait timeout is reached, the proxy sends the 250 2.0.0
x backend response to the client and the communication goes on
normally. (QUIT from the client or new MAIL..)
Attached is a strace excerpt of the LMTP proxy.

(You could check that the COMPRESS stuff made it into the released build also since Timo kindly added support for that to 2.0) Lonelycat Games has sent me a fixed build and promised to have it incorporated into the next version. Absolutely awesome. They are very good aren't they! Anyone using supported Symbian phones should definitely give Profimail a try. It's an excellent mailreader and to be honest I would like Thunderbird to support IMAP as well as Profimail! Good luck Ed W
[Dovecot] Dovecot 2.0b3: mdbox with incorrect ACL file permissions crashes
Hi, played around with 'mdbox' format some more. Converted my personal mailbox with latest Dovecot and dsync from HG: dsync convert -u lo...@yourdomain.com mdbox:~/mdbox One thing I noticed is, that dsync does not take care of existing 'dovecot-acl' files, which it should migrate/copy from my point of view, but simply skips them. Anyway I copied over the ACLs manually and forgot to set the rights accordingly. So the files were owned by 'root:vmail' instead of 'vmail:vmail' in my setup. Voilà Dovecot crashed, where it should really throw a warning or ignore the owner and work with the group permissions: Mar 2 19:27:52 spectre dovecot: imap(t...@leuxner.net): acl vfile: file /var/vmail/conf.d/leuxner.net/acls/Support/Serverloft not found Mar 2 19:27:52 spectre dovecot: imap(t...@leuxner.net): acl vfile: no access to file /var/vmail/leuxner.net/tlx/mdbox/mailboxes/Support/Serverloft/dbox-Mails/dovecot-acl Mar 2 19:27:52 spectre dovecot: imap(t...@leuxner.net): Panic: file acl-cache.c: line 295 (acl_cache_update_rights): assertion failed: (obj_cache-my_current_rights != negative_cache_entry) Mar 2 19:27:52 spectre dovecot: imap(t...@leuxner.net): Raw backtrace: /usr/lib/dovecot/libdovecot.so.0 [0x7f4d8595ffb2] - /usr/lib/dovecot/libdovecot.so.0 [0x7f4d8596001a] - /usr/lib/dovecot/libdovecot.so.0 (i_error+0) [0x7f4d859603c3] - /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da690b] - /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da4249] - /usr/lib/dovecot/modules/lib01_acl_plugin.so [0 x7f4d84da4572] - /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da472e] - /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da2aba] - /usr/lib/dovecot/modules/lib01_acl_plugin.so(acl_object_get_m y_rights+0x65) [0x7f4d84da2b85] - /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da8fd9] - dovecot/imap [...@leuxner.net 84.58.106.99 STATUS](client_find_namespace+0x17f) [0x41149f] - dovecot/imap [t l...@leuxner.net 84.58.106.99 STATUS](cmd_status+0xfc) [0x40dc2c] - dovecot/imap [...@leuxner.net 84.58.106.99 STATUS] [0x40f9bc] - dovecot/imap [...@leuxner.net 84.58.106.99 STATUS] [0x40fa6d] - dovecot/imap [...@leuxner.net 84.58.106.99 STATUS](client_handle_input+0x45) [0x40fbe5] - dovecot/imap [...@leuxner.net 84.58.106.99 STATUS](client_input+0x62) [0x410622] - /usr/lib/dovecot/libdovecot.so.0(io_loop_handl er_run+0xcb) [0x7f4d8596abab] - /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x18) [0x7f4d85969d28] - /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f4d85959eb3] - dovecot/imap [...@leuxner.n et 84.58.106.99 STATUS](main+0x191) [0x418661] - /lib/libc.so.6(__libc_start_main+0xe6) [0x7f4d851e71a6] - dovecot/imap [...@leuxner.net 84.58.106.99 STATUS] [0x4084e9] Mar 2 19:27:52 spectre dovecot: master: service(imap): child 30281 killed with signal 6 (core dumps disabled) Regards Thomas
