[Dovecot] Segmentation Fault in doveadm move under Solaris 10
by Jürgen Obermann 28 Apr '11

28 Apr '11

Hi all I want to move mails from folder test-ein to another folder test-aus with the new "doveadm move" command in dovecot 2.0.12. When I try the following I get a "Segmentation Fault" after the mail was copied to the new folder: # doveadm -v -f flow search -u g033 mailbox test-ein all 56779e33a911b84db22900005451a966 1 # doveadm -v -f flow search -u g033 mailbox test-aus all # doveadm -v -f flow move -u g033 test-aus mailbox test-ein all Segmentation Fault # doveadm -v -f flow search -u g033 mailbox test-aus all 57779e33a911b84db22900005451a966 26 # doveadm -v -f flow search -u g033 mailbox test-ein all 56779e33a911b84db22900005451a966 1 The mail now is in both the source folder and the destination folder. With truss under Solaris 10 we can see what happens (only the last few lines are shown): open64("/home/hrz/g033/Mail/test-ein", O_RDWR) = 12 fstat64(12, 0xFFBFEBA0) = 0 time() = 1303911414 alarm(5) = 0 fcntl(12, F_SETLKW64, 0xFFBFED38) = 0 alarm(0) = 5 stat64("/home/hrz/g033/Mail/test-ein", 0xFFBFEF80) = 0 stat64("/home/hrz/g033/Mail/.imap/test-ein/dovecot.index.log", 0xFFBFEA28) = 0 pread64(11, 0x00083090, 8192, 4440) = 0 stat64("/home/hrz/g033/Mail/.imap/test-ein/dovecot.index.log", 0xFFBFEEC0) = 0 pread64(11, 0x00083090, 8192, 4440) = 0 fstat64(12, 0xFFBFF1F0) = 0 brk(0x00092498) = 0 brk(0x00094498) = 0 pread64(12, " F r o m O l i v e r .".., 8192, 0) = 5135 open("/var/run/tzsync", O_RDONLY) = 13 mmap(0x00000000, 4, PROT_READ, MAP_SHARED, 13, 0) = 0xFF250000 close(13) = 0 brk(0x00094498) = 0 brk(0x00096498) = 0 open("/usr/share/lib/zoneinfo/MET", O_RDONLY) = 13 fstat64(13, 0xFFBFEE68) = 0 read(13, " T Z i f\0\0\0\0\0\0\0\0".., 765) = 765 close(13) = 0 stat64("/home/hrz/g033/Mail/.imap/test-ein/dovecot.index.log", 0xFFBFEE58) = 0 pread64(11, 0x00083090, 8192, 4440) = 0 brk(0x00096498) = 0 brk(0x00098498) = 0 open64("/home/hrz/g033/Mail/.imap/test-ein/dovecot.index.cache", O_RDWR) = 13 fstat64(13, 0xFFBFF060) = 0 mmap64(0x00000000, 57344, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANON, -1, 0) = 0xFEC90000 pread64(13, "01\b\0\0 MB811C2 MB811C2".., 8192, 0) = 8192 pread64(13, "808080D0\0\0011F\0\0\0\r", 12, 32) = 12 pread64(13, "80808998\0\001 8\0\0\00E", 12, 320) = 12 pread64(13, "80808DB6\0\001 N\0\0\00F", 12, 4704) = 12 pread64(13, "\0\0\0\0\0\002A1\0\0\01D", 12, 6872) = 12 pread64(13, "01\b\0\0 MB811C2 MB811C2".., 8192, 0) = 8192 pread64(13, " c h r i c h t " " q u".., 8192, 24576) = 8192 pread64(13, "\0\0\0\0\0\0\0\0\0\0\0\0".., 8192, 32768) = 8192 pread64(13, " l e r " < K a r l -

[Dovecot] dovecot lda aliases doesn't work
by Selcuk MIYNAT 28 Apr '11

28 Apr '11

Hi, I am trying to use dovecot as lda. I have put this line in my .qmail-default file: #|/var/qmail/bin/preline -f /usr/local/libexec/dovecot/dovecot-lda -d $EXT@$USER It is working correct with real addresses but couldn't find forwarding addresses. This is my /usr/local/etc/dovecot-sql.conf: driver = mysql connect = host=localhost user=vpopmailuser password=vpopmailpassword dbname=vpopmail default_pass_scheme = PLAIN password_query = SELECT CONCAT(pw_name, '@', pw_domain) AS user, pw_clear_passwd AS password FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' user_query = SELECT pw_dir as home, 89 AS uid, 89 AS gid FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' It is querying vpopmail table all the time but forwarding addresses are in the valias table, so it couldn't find forwarding addresses.

[Dovecot] What is the recommended way to move a message from one mailbox to another using CLI
by Uffe Jakobsen 27 Apr '11

27 Apr '11

What is the recommended way to move a message from one mailbox to another using CLI - serverside commands ? Since IMAP does not support transactional moves between mailboxes - The only thing that comes to my mind is this operation: 1) extract message from mailbox A using "doveadm fetch" 2) inject message into mailbox B using "dovecot-lda" 3) expunge message from mailbox A using "doveadm expunge" it this the right solution ? One problem with above approach is that injecting through "dovecot-lda" will trigger the sieve script - which I'm not interested in since the message have already been injected and processed once before - at delivery... Any advice is much welcome -- View this message in context: http://old.nabble.com/What-is-the-recommended-way-to-move-a-message-from-on… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] What is the recommended way to delete a message from a mailbox ?
by Uffe Jakobsen 27 Apr '11

27 Apr '11

Hi, I'm implementing a shell-script (pseudo) solution to the missing IMAP Outbox feature in Dovecot (Courier IMAP feature http://www.inter7.com/courierimap/INSTALL.html#imapsend) In order to remove the message from the Outbox once it is sent I have a question: What is the recommended way to delete a message from a mailbox (from an "external" server side program - such as a shell script) ? Can I just remove the file from the mailbox - I cannot seem to find any doveadm commands that does this task. I guess that Dovecot over time will discover that the atime and mtime of its indexes and maps does not reflect reality - or is there another (better) way to delete a message. Thanks Uffe -- View this message in context: http://old.nabble.com/What-is-the-recommended-way-to-delete-a-message-from-… Sent from the Dovecot mailing list archive at Nabble.com.

Robert Schetterer <robert(a)schetterer.org> writes: >> Anyway, why use lmtp over lda ? > > i.e avoid backscatter by overquota A clarification on this: backscatter (or rather, ambiguous NDR notices that claim many users are over quota rather than just one) is a result of a local mailer that support multiple recipient delivery in one invocation, but can only return one result code to the MTA. Since Dovecot's deliver-lda does not support multiple recipient delivery, this is not a problem. LMTP can support multiple deliveries of the same message per invocation, but replies with individual SMTP codes to avoid the above problem. It can take advantage of this to efficiently implement single instance storage if it is enabled. > performance should better too Apart from multiple deliveries or SIS, I'm not sure this is true, or significant if it were.

Multiple mirrors (seems like you have plenty of offers) preferrably is multi geographical regions, using DNS round robin with TTL 0 on www and ftp , I wouldnt bother with the wiki mirroring though.
