[Dovecot] Migration from Courier to dovecot
by Werner Detter 21 Jan '10

21 Jan '10

hi list, I've just registered to the list, so please be tolerant ;) I'm currently in the process of planning the migration from courier to dovecot as POP/IMAP-Server. I'm migration from Courier 0.58 (Debian-Etch-packages) to Dovecot 1.1.13 (Debian Lenny Backport). The conversion of the Mailbox from Courier to Dovecot will be done with "courier-dovecot-migrate.pl"-script[1], which works fine. However after running "courier-dovecot-migrate.pl" the Courier-Files still remain in the Maildir. Can i just delete those Courier-specific-files or does dovecot need them somehow (do you normally get rid of these after conversion)? It's about these files: courierimapacl courierimapsubscribed courierimapuiddb courierpop3dsizelist And those directories: courierimaphieracl courierimaphieracl Can i simply delete those with "find" ? Furthermore: is it possible to convert back from Dovecot-Format to Courier-Format? Thanks in advance, Werner [1] http://www.dovecot.org/tools/courier-dovecot-migrate.pl

[Dovecot] MUA notifications on new mail in a new folder?
by Kārlis Repsons 20 Jan '10

20 Jan '10

If deliver gets run with a non-root userid like this: < | deliver -m path/to/NEWmaildir >, I wonder, is a connected IMAP MUA automatically notified, that the new message has arrived in the new folder? As I see from some experiments with Thunderbird, it has no problems with immediate notifications of new mail in previously existing folders, however, it has problems with the case of new folder.

[Dovecot] outlook 2007 can't see public folders more than 1 deep
by Frank Cusack 20 Jan '10

20 Jan '10

dovecot-1.2.9 I have a public folder using ACLs to determine who can access it. namespace public { separator = / prefix = shared/ location = maildir:/var/maildir/shared subscriptions = no } Outlook 2007 can't see any folders except at the top level. It can create them just fine, but can't see them after quit and restart. For example, I can create the folder shared/foo/bar but on restart outlook only sees foo as a folder without subfolders (no + to expand it) and doesn't see bar anymore. In fact I can delete the folder foo in outlook and then BOTH .foo and .foo.bar directories are removed on the server. When you click on foo, the error message in the mail pane is "Cannot display the folder. The folder 'foo' cannot contain items. This is most likely a limitation of your IMAP server. In order to create a folder that can contain items, be sure not to append '/' to its name as you create it." -frank

[Dovecot] md5_verify(...): Not a valid MD5-CRYPT or PLAIN-MD5 password
by BaQs 20 Jan '10

20 Jan '10

'afternoon list! I use mysql as userdb, which contains two type of password schemes: DES and MD5-CRYPT. I read there : http://wiki.dovecot.org/Authentication/PasswordSchemes that both are supported by dovecot. Unfortunately, dovecot keeps saying: Not a valid MD5-CRYPT or PLAIN-MD5 password when looking for a user with DES encrypted password. Is dovecot able to recognize password scheme, or do I have to do something else ? I can't add {DES} to DES passwords, as this database is used with many other softwares. Thanks a lot for your help Pierre

[Dovecot] Two different issues with dovecot 1.1.13
by Stuart Rowan 20 Jan '10

20 Jan '10

Hi Timo, I'm using Debian backports.org dovecot-imapd, 1:1.1.13-2~bpo50+1. I've got two different issues, a reoccurring, seemingly harmless one about "Corrupted index cache file" (boring.txt) and one that went bonkers over the least few days (bt.txt) causing much spamming of the logs. I've made bt.txt stop happening by just rm'ing dovecot.index* : find Maildir/ -type f -name 'dovecot.index*' -print0 | xargs -0r rm ... which I realise may not be the most helpful thing to have done from your point of view. Anyway I just wanted to let you know about both of these. If one or both are already known about or already fixed by a later version of Dovecot, great and sorry for the noise! If not, and you want any more information etc., let me know. Many thanks, Stu. dovecot: 2009-07-28 10:23:16 Error: IMAP(strr): Corrupted index cache file /home/local/strr/Maildir/dovecot.index.cache: record continues outside its allocated size dovecot: 2009-07-28 10:23:56 Error: IMAP(strr): Corrupted index cache file /home/local/strr/Maildir/dovecot.index.cache: record continues outside its allocated size dovecot: 2009-07-28 08:05:54 Panic: IMAP(strr): file index-mail-headers.c: line 77 (index_mail_parse_header_finish): assertion failed: ((match[match_idx] & HEADER_MAT CH_FLAG_FOUND) == 0) dovecot: 2009-07-28 08:05:54 Error: IMAP(strr): Raw backtrace: imap [0x48dbf2] -> imap [0x48dc73] -> imap [0x48d346] -> imap(index_mail_parse_header+0x617) [0x4545f7] -> imap [0x483284] -> imap [0x483478] -> imap(i_stream_read+0x2c) [0x491d7c] -> imap(i_stream_read_data+0x46) [0x491f16] -> imap(message_get_body_size+0x108) [0x4885 a8] -> imap [0x4226c3] -> imap(imap_fetch+0x162) [0x420852] -> imap(cmd_fetch+0x23c) [0x41a27c] -> imap [0x41e46c] -> imap [0x41e51d] -> imap [0x41eb25] -> imap(clien t_input+0x63) [0x41efd3] -> imap(io_loop_handler_run+0xcb) [0x49515b] -> imap(io_loop_run+0x18) [0x4945c8] -> imap(main+0x3da) [0x426bea] -> /lib/libc.so.6(__libc_sta rt_main+0xe6) [0x7f0e851941a6] -> imap [0x418859] dovecot: 2009-07-28 08:05:54 Error: child 20007 (imap) killed with signal 6 (core dumps disabled) dovecot: 2009-07-28 08:05:56 Panic: IMAP(strr): file index-mail-headers.c: line 77 (index_mail_parse_header_finish): assertion failed: ((match[match_idx] & HEADER_MAT CH_FLAG_FOUND) == 0) dovecot: 2009-07-28 08:05:56 Error: IMAP(strr): Raw backtrace: imap [0x48dbf2] -> imap [0x48dc73] -> imap [0x48d346] -> imap(index_mail_parse_header+0x617) [0x4545f7] -> imap [0x483284] -> imap [0x483478] -> imap(i_stream_read+0x2c) [0x491d7c] -> imap(i_stream_read_data+0x46) [0x491f16] -> imap(message_get_body_size+0x108) [0x4885 a8] -> imap [0x4226c3] -> imap(imap_fetch+0x162) [0x420852] -> imap(cmd_fetch+0x23c) [0x41a27c] -> imap [0x41e46c] -> imap [0x41e51d] -> imap [0x41eb25] -> imap(clien t_input+0x63) [0x41efd3] -> imap(io_loop_handler_run+0xcb) [0x49515b] -> imap(io_loop_run+0x18) [0x4945c8] -> imap(main+0x3da) [0x426bea] -> /lib/libc.so.6(__libc_sta rt_main+0xe6) [0x7f2edf08b1a6] -> imap [0x418859] dovecot: 2009-07-28 08:05:56 Error: child 20984 (imap) killed with signal 6 (core dumps disabled)

[Dovecot] Autobuilder packages for Debian stable/i386 now available
by Stephan Bosch 20 Jan '10

20 Jan '10

Hi, A few days back I started the first automated slave builder that produces bleeding edge Debian stable packages for Dovecot v1.2 and v2.0. It uses the source packages already provided by the automated master repository (which builds binary packages for Debian testing), so that the version numbers and content are equal throughout all Debian releases. The repository is available as follows: deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-1.2 main Or, for Dovecot v2.0: deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.0 main Read this for more information: http://wiki.dovecot.org/PrebuiltBinaries#Automatically_Built_Packages I hope to add amd64 binary support soon. Regards, Stephan.

Re: [Dovecot] Oracle SQL driver

Your commit appears to ignore errors and just commit everything > that goes through? Also since nothing is actually sent before commit(), > your rollback() shouldn't need to send ROLLBACK. You right. I've corrected the transaction handling mechanism. The only thing I couldn't understand: why rollback() shouldn't need to make real ROLLBACK? In case when whole transaction was failed succeded statements will remain uncommited. Then they will be commited later on next successful transaction. May be ROLLBACK is still needed? > The "VARCHAR sqltext[2048]" seems like an unnecessary restriction on the > query length. Wasn't there a way to do this without the limit? Or in AFAIK there is no possibility to use C types in PREPARE statement. Also Oracle cannot handle unsized VARCHARs. I've increased VARCHAR size to 65535. > test_connection() seems unnecessary. Right you are. > Couldn't driver_oracle_generate_name() be simply: > static unsigned int counter = 0; > return i_strdup_printf("ORACONN_%x", ++counter); =) Right. > driver_oracle_escape_string() really should be escaping the string. I made this function to replace single quote in string with two single quotes. IMHO this should be enough. How do you think? > Kind of annoying that each query needs a cursor, even though nearly all > queries are expected to return only a single row, but I guess that can't > be helped with the current API.. Yes. There are no other ways to work with untyped statements in OCI. But Oracle claims that all these statements shouldn't produce significant performance impact. The new version attached.

Have you configured Dovecot deliver as your MDA? See: http://wiki.dovecot.org/LDA N.
